It all starts with the brain. Specifically, in this documentary, Teen Dreams, tells of the brains role in the biological process of puberty. The brain activates the hypothalamus. The interconnected nuclei of the hypothalamus release the hormone gonadotrophin to be carried throughout the body in the bloodstream. As gonadotrophins spread throughout the body they send out signals from the brain giving the body instructions for what needs to happen next. There is cell division in the testicles and the production of testosterone for males. Females experience the same release of gonadotrophin hormones into their bloodstream only instead of stimulating cell division in the testes it divides cells in the ovaries preparing the female for ovulation, menstruation, and reproduction. All of these changes are motivated intrinsically and without conscious thought to assure reproduction of our species.
Puberty is a time of rapid change from child to adolescent. It not only physically changes the body but emotionally and mentally it allows for males and females to develop a broader sense of self and tune into social consciousness. This is a time where popular culture magazines and television have a big effect on the way males and females view themselves and others. This is a confusing time for males and females. A time of not being able to remain a child but not yet having the experience or confidence in how to function appropriately as an adolescent.
In part one of Teen Dream the main character is Darren. Darren is just beginning puberty and at (2:19) into the documentary it tells of how the “command center” of the body, the brain, activates a group of cells whose role is to release the hormone gonadotrophin into the bloodstream. Through multiple processes of cell division throughout the body Darren develops a sex drive. It is shown in part one at 6 minutes 55 seconds as he is gazing adoringly at the girl next door. He is seeing her in a light colored by the hormone testosterone. In the female, it is estrogen that is the main hormone to drive sexual maturity.
Episode 2 talks of the need of both testosterone and estrogen to stimulate the reproductive process developed in puberty. Darren becomes more aggressive in the effort to attract a mate as part 2 of Teen Dreams (1:10). The body goes through changes to make it more attractive to the opposite sex. This process produces sebum at such a rate that it cannot process the extra out and it comes out as pimples. The hormonal levels of testosterone are so high it is causing him to have erections of up to 20 times a day (6:32).
Teen Dreams part 3 outlines the problems with the follicles growing faster than the hormone gonadotrophins can be supplied. The process of menstruation begins at this time. The female body constantly prepares for the possibility of fertilization. A monthly process of shedding the lining of the uterus is cued by the brain on a 28-day cycle. Even with the start of menses the female body takes a little bit longer to make a mature egg. The overabundance of testosterone and the primitive need to fight (3:00) are seen in males and the male’s testicles are producing sperm.
It all comes to a pivotal moment with Darren and Natalie opposite each other in the play Romeo and Juliet. A kiss between friends that sparks the conscious attraction and the unconscious need to reproduce. The motivations driving this action and giving it energy is internal and it consists of needs, cognitions and emotions. It all comes to a climax at (14:18) Darren’s first expulsion of seminal fluids from his penis happens at night. Welcome to wet dreams my friend.

This documentary relates very closely to chapter three as both discuss the imperative nature of the brain in motivation and emotion. In class we discussed many different motivators for behavior such as intrinsic motivation, extrinsic motivation, flow, and positive affect. This chapter and “Teen Dreams,” however, focus primarily on the brain and its functions as a motivator for behavior. Specifically, the film goes through the process of puberty for two teens, Natalia and Darren. Not only does the process of puberty cause changes in each of their bodies, but it also is a large motivator for many of their behaviors. In this film we see the influence that the hormones involved in puberty have on both Natalia and Darren’s behaviors in many ways.

As Natalia gets older during the course of the film, we see her body start to produce gonadotropin, which eventually triggers the production of estrogen in her body. Both of these hormones create new reactions in her brain which create newer and stronger emotions than she previously experienced. These hormones and the effects that they cause on her body cause her to feel anger and frustration, especially with her parents. The activities happening inside of her brain create motivation to rebel, which she does by telling her parents she is going to get a tattoo. In this case, even though Natalia probably couldn’t pinpoint her motivation for her desire to get a tattoo, chances are it is because of the new emotions she is experiencing because of her hormones.

Further on in the process of puberty, Natalia’s body also starts producing testosterone, which increases her sex drive. The increase in testosterone also motivates some of her behaviors. We can see this when Natalia makes the decision to approach David and talk to him at school as seen in part two of the film. Her increased biological sex drive has motivated her to pursue the other sex and spend more time with David, who is also clearly interested in having some sort of a relationship with her as is seen through his large amount of time spent near her.

Just like hormones affected Natalia’s behavior, Darren also experiences behavioral changes motivated by hormones in his body. As Darren’s testosterone levels increase, he becomes much more competitive and assertive. We see how increased testosterone levels motivates him to seek out a role in the play so that he can have an increased chance of getting with Natalia. Because of his biological drive for sex created by the hormones that increase in the body throughout puberty, he is motivated to seek out this role as a way of potentially gaining the sex that his body is demanding.

Additionally, we can also see how increased hormones in Darren’s body affect his behavior when he gets into a fight with David at the mall. When David confronts Darren and says that he’s not going to get Natalia, Darren’s hormones start increasing and this in turn creates an increase in aggression, motivating him to attack David. Again, just like with Natalia’s behaviors, we may not be able to understand what motivates these behaviors without understanding what functions are happening inside of the teenage brain that acts as a biological motivator to create the actions that these two characters take.

Throughout all three of these documentaries, we are educated on the ways that puberty takes form in men and women. In the first documentary, it talks a lot about how puberty changes seem to happen when you are asleep. The brain sends signals to other areas of the body telling the body that it is ready to undergo puberty. In males, the hormone testosterone runs through the blood stream and gives males the desire and motivates them to reproduce and have sex. There is a similar hormone in women that have this same effect; this hormone would be estrogen. Estrogen changes the girls body eventually into a sexually mature woman. In women, the brain signals puberty to start later than it does with men, but estrogen causes women to grow and mature more rapidly than testosterone does to men. A large amount of estrogen in the body causes the body to have a growth spurt.
In part two of the video, it takes about how in the male body, the brain can convert excess testosterone into estrogen. It takes quite awhile to get the estrogen to build up, and this is why males mature more slowly than females mature. Women can also get the male hormone, testosterone, from their kidneys into their blood. Their blood carries the testosterone to their brain, and then this motivates the women’s reproductive circuit. Everyday, the level of estrogen and testosterone in the male and female’s body rises to motivate them to have sex and to prepare them for sex.
There were several times throughout the second video when you could see that the increase in testosterone was having an effect on Darren. In the morning when he was super enthusiastic getting ready for school, when he started to get acne on his face, when he tried out for the lead role in the school play, increased aggression, etc. You could also tell that the estrogen levels in Natalia were increasing because she was motivated to put make up on, dress up, got super excited when she received texts about a boy, her body was changing shape (breasts were growing), etc. The body undergoes several changes to attract a mate, like I talked about earlier with the body changing shape. In women this comes in the form of larger breasts and buttox. In men, muscles start to grow (biceps), and other parts of the male anatomy. Another way that the body tries to attract a mate is by growing hair.
When the female body stops producing estrogen, the body starts to get acne and the body will shed the womb lining. This motivates the female body to get her period. During this time, the female body undergoes a lot of discomfort. Also during this time, Natalia gets quite emotional because of her appearance and her body changing. These types of changes are examples of intrinsic motivation. This is because the body undergoes these changes to make you attractive to a partner or to satisfy yourself. All of these processes would not be able to happen without a signal from the brain telling the body, hormones, and organs what to do.

Terms: testosterone, estrogen, motivation, hormones, intrinsic motivation, emotion

“Teen Dreams” was made specifically to educate viewers on the causes and effects of puberty, but it relates much more to Chapter 3 of our book than just being about the brain. In Chapter 3, it was very clear that motivation is not always a conscious decision made by the individual. Many of our instincts and drives are started from the hormonal changes that start inside the brain. For the purpose of the assignment, I will focus less on the puberty aspect, and more on the behaviors and how the brain is motivating them.
Natalie experienced many new thoughts and feelings during this period because of all the reactions going on in her brain. Because of these feelings, her behaviors altered as well. In one scene, she gets very frustrated at her parents for not allowing her to get a tattoo. When asked why she wanted one in the first place, she didn’t seem to know. Her acting out like this was caused by the inactive parts of her brain coming to life from the hormones stimulating new nerve endings, and these powerful emotions were too much for her to handle. These changes are most likely happening in the hypothalamus and anterior cingulate cortex which are associated with feelings, mood and decision making. Another new behavior she may be unfamiliar with is the drive to want male attention. Suddenly she is having dreams about boys and she is interested in both David and Darren. She starts wearing makeup and perfume in hopes of seeming more attractive. This change in behavior tells us that this is a new concern of hers, though she may not truly understand why since she hasn’t really experienced the full extent to puberty yet. This may be due to her septal area making new connections and helping her build her sociability and sexuality.
Darren is also experiencing some changes in his body and behaviors. One of the most obvious, abnormal behavior he showed was aggression. In the mall, he made it clear that he was interested in Natalie and when David stepped between them, he felt a sure of testosterone and adrenaline. Because he isn’t mature enough to handle it yet, he decided to go after David to establish dominance. His brain is so distracted by wanting to impress Natalie and the instinct to “win” over David that he acted out of character. Though many parts of his brain are going though the same process as Natalies, he has much more testosterone and his main focus seems to be sex. His reticular formation, hippocampus, and septal area are all keeping him focused on arousal, behavioral inhibition and sexuality. This documentary focuses purely on the development during puberty, but these structures of the brain are continuing to work though out our lifetime. Similar to the same concept, we may find it hard to distinguish if peoples behaviors and motivations are due to chemicals in our brain or our cognitive process.

In this documentary called “Teen Dreams” there are two main characters that the film is focused on. The male character Darren, will go through a growth experience from the hormone testosterone as we watch him throughout the film how his body, and his mind changes the way he is motivated by outside stimuli. The female character Natalie, will go through a similar process of growth from the hormone estrogen. As she grows, her experience, although slightly different from Darrens, details her growth until she reaches the point her first mature egg bursts out of the follicles to the ovary wall and carried through her fallopian tube.

In the beginning, we are greeted to an introduction scene where two immature children are playing together showing intrinsic motivation, basically having fun just for the sake of having fun. The film quickly introduces gonadotropin which produces the male hormone testosterone for Darren and estrogen for Natalie. The soaked cells flow through the bloodstream as their testicle / ovary evolve. At this very state, it’s still the beginning stage, we see Darren walking to school with a intimidated demeanor as the camera focuses on his eye movements especially towards the older students at the school, as well as purposely avoiding the popular group showing signs of shyness as an emotion. However, his hormones spike during the scene where he is waiting for band practice and catches Natalie, her next door neighbor, singing. The camera focuses into his eyes as it dilates, while Darren is occupied staring at Natalie just smiling at her beauty and presence.

The film gives us the opportunity to see Darren and Natalie finally interact in a conversation after Natalie’s hormones escalated, resulting in a tattoo comment followed by an argument. During the interaction between Darren and Natalie, the topic was of course about tattoos. Once Darren asked where she was thinking of getting a tattoo, she showed parts of her body which triggered Darren’s testosterone which disrupted his focus, not allowing him to form a conversation or even a sentence. As time passes, both individuals grow physically, the skeletal structure grows, and their posture, the way Darren walks and talks, has changed due to these hormones. From a shy boy avoidant of trouble to a bad boy-like image trying to get his girl, Darren’s attitude and personality changes drastically throughout the film. Natalie experiences sexual attraction, experimenting with makeup, as well as maturity since growth spurt for women matures faster compared to males.

The narrator refers to the primal animal instincts quite often, as we see in the later scenes Darren and Natalie’s crush fighting at the mall trying to fight for her love. Darren’s aggression and past envy when he “didn’t have it” gets to him as he releases his anger in a fight against the drama crush of Natalie’s. At this point Darren wins the battle, but his testosterone level is still extremely high, instead of focusing on Natalie, he looks at Simone and gives her a flirtatious eyebrow raise as she smiles back. Referring back to the primal instinct, Darren, in his head, is the man and above Natalie’s crush as he came out the stronger individual giving him flow motivation to reach his goal. I’m not sure what the goal was as the ending doesn’t specify if Darren and Natalie are now in a relationship. However, he got her attention and his self-esteem boosted due to that fact that she liked him back to an extent which seemed like what Darren was after.

Much like chapter three; Teen Dream relates motivation and emotion to certain parts of our brain. Teen Dream focuses on the stages of puberty by describing what happens in our brain to be motivated to certain acts. Such acts could include sexual intercourse or playing an active sport. During puberty, our bodies change very quickly and do strange things. In the movie, we see how Natalia and Darren both experience puberty but also see how their motivated behaviors change.
Certain cells are activated in the brain creating signals to the blood vessels known as gonadotrophins. Darrin changed quickly from part one to part two due to his testosterone levels growing rapidly. When the gonadotrophins split into new cells it produces new sex hormones. This is when Darrin is able to reproduce. During this part, his body begins to change where he begins to think about girls and sexual intercourse. Throughout each stage of the movie Darrin slowly progresses more and more with his anger and sexual drives.
Natalia, on the other hand, started producing estrogen carrying signals from her brain to her body. Estrogen makes permanent changes in the nerve endings creating new connections. We noticed more happier emotions at the beginning but also, she began to feel anger. For instance, when her father complained about her wearing perfume or when a boy moved his hands up and down on her. The anger and frustration caused a motivational drive for her to lash out.
As her body begins to produce testosterone, we notice changes in her behavior as she begins dating boys. As we begin puberty, we start to notice the opposite sex and have a strong interest in finding out more about them. Like Darrin does about Natalia and Natalia does for David. We are motivated to impress the opposite sex because the gonadotrophins send signals throughout our blood stream producing a sexual drive.
Darrin needs estrogen like Natalia needs testosterone known as adrenal glands. Darrin begins to compete in sex because he becomes jealous and wants Natalia's attention. This is due to his testosterone levels rising. The hypothalamus begins to come into play here; this part of the brain regulates the basic biological functions. The hypothalamus is connected to the autonomic nervous system which includes involuntary control in the organs. An involuntary control for Darrin would be when he becomes erected for no reason at all. An increase in aggression, increases the levels of testosterone. This occurred in the film when Darrin wanted to fight David because David made him weak and less powerful.
It is hard to understand what motivates us or why we are motivated in the first place. Natalia and Darrin both play an excellent role in this because they were confused as to what happening in their bodies; just like any teenager experiencing puberty.
Terms: hypothalamus, gonadotrophins, autonomous nervous system.

The brain carries out cognitive and intellectual functions as we seen in this documentary. The brain activates the hypothalamus which releases the hormones to be carried throughout the body in the bloodstream. These hormones send signals to the rest of the body about what to do next and what changes are to be made. This process is quite lengthy because some of the processes take buildup of testosterone to turn into estrogen for the male body which is why it seems that girls mature at a younger age. Although this is not true either, females simply mature faster in appearance while males’ maturity starts inside first. Males brains convert extra testosterone into estrogen which is the reason whey males mature slower than females to the public eye. However, before this process happens the body reacts to the extra testosterone in the form of acne as we see in Episode 2 of Teen Dreams at 4:17. The extra sebum produced from testosterone causes the pores to become clogged and infected which causes the pimples we all hate. Males hormones peak at night which is possibly the cause of morning wood and how a male can go to bed with no acne and wake up in shame. These changes happen intrinsically without us having to put thought into it.
Puberty happens rapidly and not just in appearance. Many of the physical changes cause our brain to fall behind as seen in the documentary when Darren falls while dancing because his mind can’t keep up with sending signals to the body since it is changing so rapidly. While Darren is battling outward aspects of puberty, Natalia starts the inner process of puberty. The documentary made note of this when she started her menstrual cycle. This was essentially one of the last processes that females go through in puberty. Before the menstrual cycle starts the female body takes the excess estrogen and turns it into testosterone which causes hair to grow in so called unwanted places however this is to help eliminate body odor so while it may be ugly to the eye it is pleasant to the nose. In chapter three of our book it goes into detail of how the brain is responsible for our bodily functions, and how without the brain triggering testosterone/estrogen to be produced puberty wouldn’t happen.
Teen Dreams put things into prospective on how the body goes through changes and how the brain must adapt to properly function. While the brain is responsible for the changes we go through, it needs time to process and grow as well to be able to send the right signals out to our ever-growing body’s during the puberty stages.

From watching this documentary, I found that it relates very closely to chapter three of the textbook which we just read. It talked a lot about the biological motivation behind some behaviors for both males and females. It explained these biological motivations through the process of puberty. This documentary really focused a lot on hormones and how they play a role in the drives and motivation of an individual. For example, it shared in depth on the process of puberty that both the girl and boy go through. I thought that this related closely with the material that we just read in chapter three where it explained about the release of hormones and how they can affect your mood, behavior, and ultimately your motivation to behave in certain ways.
One example of how the documentary demonstrated how puberty plays as an unconscious motivator in females was in the scene where Natalie decides to wear perfume and her father sniffs it out. The documentary goes on to explain how estrogen is causing permanent changes in her body which are caused by the hormones. The documentary suggests that these changes are the outcome of newly stimulated nerve endings that are making new connections. Thus, this can cause changes in behaviors, attitudes, and emotions, which might have been the cause of Natalie’s outburst directly following this scene where her father was not in agreement with her about wanting to get a tattoo.
One really interesting thing that the documentary discussed involved the gonadotrophin hormone that is released from the hypothalamus in the brain. This hormone is the cue for the body to get moving on puberty. In both boys and girls, this hormone will allow for the pituitary gland to release even more hormones that will help with the puberty process of each sex.
Another point that this documentary made, that was also discussed in the text, was that often times motivation to behave in a certain way is unconscious. In the documentary this was demonstrated by the scene where Darron and Natalie are on stage performing the scene where they kiss in Romeo and Juliet. In this scene, it created a conscious attraction between the two where they are aware of their feelings. It also sparked an unconscious motive to reproduce.
On a lighter note, this documentary definitely helped me to understand why young teens can be so awkward when it comes to interacting with the opposite sex (in most cases). I really never realized the exact cause for the awkward interactions or situations where a girl or boy might act a strange way, like picking on the person they like or being tongue tied in a conversation, but are unable to explain why that particular behavior occurs.
Throughout the documentary, it constantly related to and discussed how biological processes, such as puberty, play a role in motivation and the emotions. In addition, it explained how the hormones produced during puberty play both conscious and unconscious roles as motivators which I was able to find a lot of connections to from our assigned readings.

In episode four of “Teen Dreams”, the show follows the course of puberty in a boy and a girl. Throughout puberty, the show follows various events throughout the stages of puberty which will be explained by several key concepts, such as motivation of sex, development and use of hormones, and finally internal and external motives.
The entirety of the episode focuses on puberty, but it also deals with idea of sex. Puberty is a necessary step in development to become physically (such as developing sperm and eggs) and mentally (motivation to reproduce) capable to reproduce. Which then comes to the first key point, motivation of sex can be looked at by various state of expression. For example, throughout the episode, the boy and the girl went to through various physical changes from height to development of sex cells. As for mental changes, they would engage in activities they wouldn’t normally be engaged. The boy would fight with the boy, in spite of anger, was done so to impress the girl. He also went on to join the play just to be closer with the girl and to get her attention. Both instances where behavior and engagement were expressed. The girl on the other hand, engaged in a more subtle approach. Running to meet up with her friend and going to the mall. One scene, in preparation for the play, was looking at a selection of perfume. A behavior in which she was engaging to possibly impress others and even a mate.
The second key concept, development and the use of hormones, is another aspect which helps in terms of explaining key motivation. Sometimes the decisions, especially the ones from the last example, are often ignited by the use of hormones. Steroids like hormones, in large quantities in male and smaller in female, oftentimes are connected to key behaviors such as aggressiveness and competitive behaviors. Like I mentioned before where the boy engaged in physical combat with another boy, higher levels of testosterone and external influences have motivated him to engage in the said activity and to impress the mate (even though It didn’t go as planned).
With the physical contact, another part that can explain the incident was the use of the amygdala. The amygdala may be the motivator behind a lot of what happened in the episode as it is associated with emotion and motivation. Anger when he engaged the other boy at the mall and anxiety at the play or even jealousy when she saw her friend go out with the other boy.
And finally for external and internal motivation. You can say one of the biggest internal motives is the basis of the entire episode: maintaining bodily function (with food) for development of puberty which in turns motivates reproduction. Another internal motivation includes the boy’s cognitive motives to join the play to be closer with the girl. As for external motives, pimples were one motivation that they both try to hide. Pimples are the bane of teenagers, especially in social places such as schools. So when the boy used makeup to cover them, he was externally motivated by social peers in anticipation for teasing (even though he ended up being teased for wearing makeup).

Internal motivation
External motivation

Puberty is a complex process that takes years to complete in humans, and this is shown in depth through Darren and Natalie in this documentary. Chapter 3 in the textbook discussed specific regions of the brain and how they are related to motivation. Similarly, this documentary focused on the brain’s role in puberty. When Darren is eight years old, his brain begins to release gonadotropins into his bloodstream while he is asleep, thus beginning puberty. Eventually, these gonadotropins stimulate the production of testosterone in Darren’s testes, and this is when he starts to develop a sex drive. For Natalie, gonadotropins flood her bloodstream at night as well, but these create the production of estrogen from the follicles in her ovaries. The estrogen in her body stimulates nerve endings and manufactures new pathways. Natalie has trouble managing these new additions, and when her father asks her if she is wearing perfume, she has a bit of an emotional outburst because she does not yet know how to balance them. On the other hand, Darren’s testosterone-filled body and brain have made him see Natalie as more than a neighbor and friend: he is now thinking about her in a sexual manner. The hormones and neurotransmitters in his brain spur his motivation to find a mate as he begins to feel the effects of having sexual needs. In both teens, their cognitions have shifted from those of children into those of young people on their way to adulthood with Darren thinking more in sexual terms and Natalie thinking in terms of a desire to be independent.
When Darren finds a way to act as Romeo alongside Natalie who is playing Juliet in the school musical, he is feeling this motivation to be competitive against David because his testosterone. This action is an example of extrinsic motivation because he wants to feel the reward of getting closer to Natalie. In order to accomplish this, he exhibits the behavior of convincing the director to cast a Romeo with a higher voice so that he could put himself into competition with David in hopes of removing him from Natalie’s immediate radar. Natalie begins menstruating when one of the follicles in her ovaries producing most of her body’s estrogen dies and her estrogen levels plummet while her testosterone levels are higher. This first period is not prompted by a fertilized egg, but the body’s motivation to begin menstruation is biologically-based and can be explained through an evolutionary lens as a way to ensure that she is on the fast track to being able to reproduce. Puberty’s entire purpose is to turn children into sexually-mature adults that are attractive to the opposite sex. Some of the effects of puberty are less than desirable, though, and the brain can have a hard time adjusting to all the changes going on in the body. For Natalie, this happened when her estrogen levels dropped right before her period and the testosterone in her body trapped sebum in her pores. For Darren, the stretching of his vocal cords caused his voice to break during the musical, which embarrassed him and made him not want to sing anymore. The onset of puberty causes an influx of new motivations for preteens, and learning to manage this onslaught is a learning curve we all go through.

The documentary starts off by discussing the properties of the brain, and the role it plays in puberty. Chapter three in our text books also talks about all of the functions that our brains have before and after maturity. The first steps start with the hypothalamus. It creates gonadotropin which is then carried throughout the body and starts the puberty phase in both males and females. In the video Natalie, initially, starts growing before Darran because the female sex hormone estrogen builds up and starts growth. Males also produce small amounts of estrogen but not enough to cause any significant growth. It wasn’t until Darren's body made excess testosterone that he started his noticeable growth.
For females, when they begin puberty their brains are forming new neural connections which is an overload for their emotions. They do not know how to handle the influx of information going on in their head so they start to lash out. This is shown when Natalie tells her parents that she wants to get a tattoo. When they tell her no, her emotions get the best of her and she begins to yell at them. As she progresses through puberty she also starts forming a sex drive. She begins to become more interested in males and starts working on ways to attract them. Natalie would talk to her friend about David, spend more time around boys, and even put on makeup in order to seem more pleasing to men. Also, her sex organs begin to create eggs and she gets her first period. Since females create more estrogen than males they go through this process first.

As Darren started going through his changes he notices a few external signs of puberty. The testosterone overload causes his sebaceous glands to enlarge and create sebum. This gaseous buildup can become irritated and infected which leads to acne formation. There are some internal things going on as well. The testosterone leads to higher aggression. This could be because our ancestors would fight one another to attract a mate and show dominance. This is exemplified when all the kids were at the mall and Darren got into a fight with David. The high rush of emotions and chemicals within the body are difficult to control for kids who are not used to them yet. Darrans body is also preparing his sex organs for maturity. He experiences several unintentional erections throughout the day. When his body has finally hit sexual maturity he experiences his first nocturnal emission. As he continues to progress through puberty his body grows and develops muscle. As he grows his vocal cords lengthen and his voice begins to deepen.

In the documentary, “Teen Dreams”, we learn that puberty always starts in the brain and for whatever reason always starts at night. While the boy is sleeping the body releases chemicals into the blood stream called hormones that will become the building blocks for Darrin to start puberty. For boys those building blocks come from a hormone called testosterone and for women that building block is called estrogen. These two main hormones will now set up the body for sexual reproduction for the rest of their lives and it is all controlled by the brain. After learning about some of the brain structures and how they are related to the motivation and emotion part of our lives, this video explains how the brain creates and controls our need for one of our basic functions as a human, reproduction. Every night during adolescents the body gets flooded with both hormones in both boys and girls triggering changes in the body. Not only does it make changes to both Natalia and Darren, it also changes them mentally in order for them to further on their genes. Natalia and Darren will mature at different rates because of the different imbalances they will experience between testosterone and estrogen, but it all starts the same with the release of gonadotrophins into the blood stream which lays the blueprint out for what is about to take place.
In the case of Natalia, the release of gonadotrophins will start the production of estrogen which will start the splitting of ovaries cells in the body. Ovaries are the female eggs that are needed to reproduce and over the next 5 years her body will prepare for things like ovulation, menstruation, and reproduction. One of the things I learned from this documentary is that just because Natalia had her first period doesn’t mean that she is ready to reproduce. In Darren, the release of gonadotrophins causes sperm cells to start to split and divide over the next few years getting him ready to reproduce as well. Hormones don’t just change adolescent teens physically it also changes their motivations and emotions towards the opposite sex. With the release of the sex hormones in their bodies, both Natalia and Darren are motivated more than ever to engage and discover the opposite sex. A couple of examples of this came in episode 2 after the body started to physically and mentally change. The testosterone in Darren’s body, he becomes more aggressive because of an evolutionary trait to try and attract a suitable mate. This high level of testosterone also can cause him to have up to 20 erections a day. Natalia also has testosterone in her body, though not as much as Darren, and this sparks her sex drive causing her to want to spend more time with boys and causing her to have stronger emotions and thoughts. So when we argued more with our parents as teenagers it technically wasn’t our fault. This video went with chapter 3 well because puberty is a great example of how the brain controls our motivation and emotions.

Chapter 3 of our textbook covers the biological process that takes place inside of our bodies that ultimately leads to all of our motivations and emotions. The process, while highly complex, can be broken down into four main stages. The first stage is the occurrence of an external event outside of the body that leads to an activation of biochemical agents, neurotransmitters and hormones, inside of the body. These agents make up the second stage as they are created within the body and flow into the brain and activate certain brain structures. The third stage involves these brain structures being stimulated by the biochemical agents. This stimulation leads to the final stage where the stimulated brain structure creates a psychological experience that a person can recognize such as hunger or fear. While this whole process may seem long, it actually takes place in a matter of seconds.
The drama documentary “Teen Dreams” has several examples of this process happening. One such example is a scene where the character Darren decides that he wants to enter into the school play. As he has just entered puberty at this point in the film and is dealing with the foreign feelings of sexual attraction, it is a good example of how the biological process can guide behavior without an individual realizing it. Let’s walk through the process that Darren went through that lead to his decision to join the play.To start, he saw his friend Natalie, who has also just started puberty, practicing for the school play in the gym. Ever since he began puberty, Darren’s body had started to produce the male sex hormone known as testosterone. Seeing Natalie up on the stage singing caused a reaction inside of his body that involved the testosterone starting a chemical reaction inside of his brain involving his reproductive system. While it isn’t named in the film, based on the information that is in our textbook, we can conclude that the involved brain structure that is stimulated is the hypothalamus. The hypothalamus is a part of the brain that is responsible for pleasurable feelings in relation to consuming food or drink and mating.
Going back to the film, we see that Darren has a chemical reaction take place in his brain involving the testosterone that is now being produced by his body. What this testosterone seems to be telling his brain is that Natalie is his perfect mate and thus his behavior changes into the pursuit of making her his mate. A later scene shows that Natalie has started dating another boy, David, and Darren sees this as a threat to his pursuit of making Natalie his mate. An effect of high testosterone levels in the body is causing an individual to become more comparative. This is ultimately why Darren decides to join the play, because his hypothalamus recognizes potential pleasure in having Natalie as a mate and being in the play is viewed as the best method to get Natalie as a mate.
To summarize, let’s walk through the four stages previously mentioned and apply them to Darren’s situation. First, there were the environmental events of seeing Natalie singing and seeing her with David. Second, there was an increase in the testosterone levels in his body. Third, this testosterone stimulated parts of Darren’s brain, specifically the hypothalamus. Finally, the hypothalamus took this stimulation to mean that Natalie would bring pleasure, so it directed Darren’s behavior to find a way to get her as a mate. This behavior involved first approaching Natalie, but when that method failed and he saw her with David the high level of testosterone kicked in and Darren followed his competitive instinct to beat David to get Natalie by joining the play.

The documentary, Teen Dreams, discusses the brains role in the process of puberty. Chapter three focuses on how various parts of the brain and how it is involved with emotion and motivation. The documentary follows two teens that are going through puberty, Natalia and Darren. This is closely related to the chapter because they both discuss how specific brain structures and the release of hormones play a role in motivating young people.
At the beginning Darren and Natalia start as two friends who have no interest in the opposite sex or being romantically involved with anyone. The beginning of their journey through puberty begins with the hormone gonadotrophin being released at night from the hypothalamus. It then travels through the body and begins sexual and reproductive function. For Darren, inside his testicles, cells begin to divide and build factories that one day will produce sperm. When gonadotrophin releases in Natalia’s bloodstream, this begins development in the ovaries preparing the female for menstruation and reproduction. Without realizing that this process is going on, we are being prepared to reproduce to keep our species going.

Gonadotrophin begins the development of testosterone (the main male hormone) and estrogen (the main female hormone). The release of testosterone in Darren’s body increases his sex drive. He begins to see the girl next door as a potential mate. This new experience of a sex drive causes him to begin to dream and fantasize about the opposite sex. These new sensations are causing Darren to have around 20 erections a day. The increased hormones cause his pores to become clogged and acne to form, his vocal chords to elongate, and bones to grow as well. I thought it was interesting that voice cracks and coordination are affected by your brain not being able to catch up with how fast your body is developing. Testosterone is not only creating changes to his body, but also develops extrinsic motivations. Darren became interested in joining the play only to become closer to the girl of his dreams. As he becomes more motivated to please his sexual desires, the increased testosterone levels also cause him to become more aggressive. He becomes angry and fights another boy in his grade.

As Darren is dealing with increased levels of testosterone, Natalia is dealing with new levels of estrogen. The varying levels of estrogen also causes her to go through some changes as well. She begins to become more emotional causing her to lash out at her parents for not allowing her to get a tattoo. Both will have estrogen and testosterone flow through their bloodstreams. Testosterone causes Natalia’s sex drive to also increase. Now Natalia notices the males around her and wants to begin dating. She begins to start to do activities that will make her seem more attractive. She cares more about her appearance and purchases perfume in hopes of getting male attention.

The documentary showed us in various ways of how the process of puberty can impact our emotions and motivations. Before puberty, Darren and Natalia had no interest in sex. The hormones being released through the bloodstream prepares the female and male body for sex and unconsciously fuels the drive to reproduce.

This film was a pretty good representation of what happens to two kids once they hit puberty, and the effects that go on during that time. The movie talked about the impact of testosterone and hormones in both Darren and Natalie. In Natalie`s body, the adrenal glands pump testosterone into her body in order for her to have the drive to talk to the boy, and further the conversation. Once the hormone is released from the adrenal gland, the bloodstream acts as a neurotransmitter and carries the hormone to the brain for it to be used. We also saw the effects of testosterone in Darren, when he wanted to be with Natalie so badly, he went and told the director of the play that he was better than the other boy. This was a cause of testosterone. Not only does testosterone help Darren with wanting sex, and it gives him the drive to go and get it. The impact of sex and reproducing to further their genes was the main point of the videos. Testosterone and Estrogen were talked about a lot, because they are the two most powerful hormones during puberty. They each work to transform and "take over" the body so that it can be ready to reproduce.
The hypothalamus is also brought into the equation in terms of sex, and sexual partners. The hypothalamus regulates our needs for important biological functions, like eating, drinking, and mating. While the hypothalamus was not mention many times in the video, it does play a part in choosing our mates, and acting upon our needs to mate. The hypothalamus sits on top of the pituitary gland, the master gland of the endocrine system. When our body needs to increase arousal, the hypothalamus stimulates the pituitary gland in order for it to send hormones through the bloodstream to stimulate the adrenal glands to release its hormones. Doing this will trigger the "fight or flight" response. So before Natalie could release her hormone from her adrenal gland, the hypothalamus first had to make her feel that arousal by stimulating the pituitary gland.
One effect of testosterone is that it is in our bodies to attempt to make us look more appealing to others, hopefully triggering a desire to mate and reproduce in order to carry on the genes. One way this happens is through height, and growth spurts. Once Darren`s body had enough testosterone to turn into estrogen, it allowed him to have his growth spurt. We also saw this with his muscles. Testosterone is used in the muscles to expand them, making them bigger, and more attractive to potential mating partners. These are two more examples of how testosterone can do more than just excite us to mate, but also help us to get a mate.
Testosterone can also do things in an attempt to help, that do not exactly help with finding a mate. As we saw with Natalie, she began to grow hair from her armpits. This was a attempt to help Natalie find a mate. However, because the hair attracts sweat, and the sweat carries bacteria which releases a bad smelling odor, it made her less attractive to Darren.
The documentary did a good job showing us what it is like on the inside of our bodies, and how testosterone and other hormones make up our changes, and our desire to reproduce.

The “Teen Dreams” documentary and chapter three in our textbook come together linking puberty and the human brain, along with hormones causing certain behaviors. Darren and Natalie are the two main characters in this documentary that are growing up together and initially going through puberty together. Combing the documentary and chapter three, the common area is the brain, the control center for emotions, motivation and puberty. Both Darren and Natalie experience puberty, which leads to having emotions that they may not have experienced before. Those emotions lead to dramatic behaviors, such as lashing out on parents, or picking fights with your crushes’ current boyfriend. Their bodies are changing and cause aroused thoughts, and more motivation towards the opposite sex, and well sex in general. The documentary provides a good example of how the brain releases hormones and triggers these behaviors in our bodies, resulting in some uncontrolled emotions and motives.
Darren and Natalie’s bodies release hormones while sleeping, which will slowly start preparing each of them for puberty. Darren’s body releases testosterone and Natalie’s releases estrogen. While both kids have both hormones in their bodies, one is required more over the other for puberty to start. Along with other hormones in the body, the brain controls testosterone and estrogen. The brain is the control center, and the hypothalamus helps start puberty be releasing gonadotropin, which is produced in both males and females. The brain is in control of these hormones, and in the documentary, Natalie starts to develop and mature faster than Darren. Natalie’s hormones are building and growing faster. Darren didn’t start developing until later, when more testosterone was made and Darren grew.
Testosterone in Darren’s body made him more aggressive and competitive toward his feelings for Natalie. For example, when Natalie decided to go out with David, his emotions made him go join the school play, knowing that Natalie was in it and he wanted to be apart of what she was doing. Darren joined he play to be closer to Natalie, he wanted to be near her. Darren took pleasure in seeing Natalie and his hypothalamus took note of that feeling, and thus he became motivated to join the play from that feeling. Another example is when Darren picked a fight with David at the mall after Natalie showed up. His hormones and emotions got the best of him and his actions lead to physical aggression towards David. An example of Natalie’s emotions over concurring was earlier in the documentary when she told her parents she wanted a tattoo and she became extremely upset and aggravated they said no. She argues with them and then storms out.
Both Darren and Natalie go through internal and external sex changes. Internally both bodies are releasing hormones and creating more neurological connections in the brain. Natalie’s ovaries grow and have an increased blood flow to other parts of her body. Darren experiences multiple involuntary excretions and his body undergoes a growth spurt and grows more muscle. His hormones allow him to become sexually mature, but at the cost of his excretions and pimples on his face, he lacks the physical attraction he seeks of the opposite sex (at the time). Darren also has a change in his vocal chords. As he matures, his voice becomes deeper but at the time his body wants to start making that change, Darren is performing in the play and his voice starts to crack. Natalie’s body changes relatively the same. Natalie grew a little faster than Darren did, but her hormones allowed her to have a pimple free face longer, until her body decided otherwise. Natalie grew more hair due to puberty in other regions of her body, including her armpits that house some odor causing bacteria. While rehearsing in the documentary with Darren, her odor becomes imminent as she sweats and Darren notices.

In both chapter 3 and the documentary they both explain in detail how the brain works with motivation and emotions. They both explain behaviors that motivate us to do something, an example eating. “Teen Dreams” talks more about puberty and how it affects our motivation and emotions. Like it said in the documentary boys and girls go through the stages of puberty at different times. It influences the behavior that they give off during this time. Not only does it change the behavior that they go through but also their bodies. The hormones they both have are influences by puberty.
The documentary talks about how the changes seem to occur most when you are asleep. The brain tells the body that it is ready to go through puberty. For men testosterone is what runs through the blood, which motivates them to want to reproduce and to have sex. For women it is estrogen that runs through their blood and makes them want to reproduce and have sex. For women though puberty starts later than it does in men. Women go through puberty faster then men do though. You can tell when girls are going through puberty or are just about to start because they hit a growth spurt. For men the extra testosterone is turned into estrogen. It takes estrogen a long time to build up and that is males are going to mature slower than women. Women can get testosterone from the blood in their kidneys. Once the blood reteaches the brain it motivates women to want to reproduce. Each day of puberty the level of estragon and testosterone in both men and women go but making them want to have sex and getting their bodies prepared to have sex. In the documentary you could see it in Darren by how he was getting acne, had a lot of energy, wanted to join the play because of a girl, and then he got aggressive too. With Natalia you could tell when she was going through puberty because she wanted to wear make up, would dress up more, was excited over talking to boys, and her body was changing. Another change they went through was hair growth. The way the body change is so that they can attract a mate. For girls when the body stops making estrogen they start to get acne. They also will start to get their period. This can be very uncomfortable. With the body changes girls then start to wear make up and might dress differently. This is to make themselves feel better but to also attract a mate.
The body changes so much during this time and it can be a hard time for both sexes to go through. What can be helpful is that most of their friends are going through the same thing. It is all a process. A process in which the brain is telling the body and hormones what to do in order for the people to grow.

The documentary “Teen Dreams” closely relates to Chapter 3 by giving us an inside look at what happens to Natalie and Darren as they experience puberty, and its effects on their motivations and emotions. In several scenes, Natalie and Darren’s biochemical changes affect their thinking brain, motivated brain, and emotional brain causing them to behave in ways they normally would not.
In part one, when Darren’s testosterone level is beginning to rise, we see him attend the school’s auditions for a musical. Darren’s testosterone triggers his reproductive circuit, thus causing him to feel and experience a sex drive. After seeing Natalie sing, he no longer thinks of Natalie as just the neighbor-girl but as the “woman of his dreams”. Darren’s thinking brain has been altered. Also, we see Natalie’s thinking brain transform when her estrogen begins to stimulate feelings for the opposite sex, primarily David, the first male lead in the musical.
In the scene where Darren is negatively affected by seeing Natalie and David at the mall, we see his Motivational brain become altered by his testosterone. Due to testosterone being the hormone that underlies the effort of mating, it motivates Darren to audition for the lead role in the play to get closer to Natalie and for his brain to get closer to sex. Without even knowing it, Darren’s motivations have been altered due to his sex drive from his reproductive circuit. In Natalie’s case, we see her Motivational brain change through the use of cosmetics and perfume. The build-up of estrogen causes her to want to be more attractive to “mates”, resulting in her want to use perfume and make-up.
Lastly, we begin to see Darren and Natalie’s emotional brains begin to change. In part three of the documentary, both Natalie and Darren are reaching sexual maturity and experiencing full-force the power of their hormones. Darren’s high levels of testosterone cause him to feel extreme anger or aggression very quickly, resulting in an altercation between him and David, over Natalie. Darren’s quick switch of emotions from joking and poking fun to anger and aggression also stemming from his sexual and aggression circuits being overlapped in his brain. At this point for Natalie, her estrogen has plummeted to prepare for her first period resulting in mood swings/emotional sensitivity and acne. We see these two forces at work when David visits Natalie but ends up insulting her and her insulting him; a break-up. Then we see Natalie become jealous and sad when she looks out the window to see her best friend Simone heading over to Darren’s house next door.
In many of these scenes, we see how Natalie and Darren’s motivations and emotions are affected by their rise in biochemical agents: testosterone and estrogen. This documentary closely relates to Chapter 3 by giving us an inside look at what these biochemical agents can do to our thinking brains, motivated brains, and emotional brains. Also, “Teen Dreams” provides excellent examples for how day-to-day events trigger biochemical agents into actions and how the biochemical agents then stimulate specific brain structures.

Daron was motivated to try out for the musical because that meant he got to spend time with Natalie. External incentives pushed Daron to participate in the musical. This was also caused intrinsically because the reason he wanted to spend time with Natalie because the emotions he had for her caused by his testosterone boost while going through puberty. Social context came into play on his performance. You could see how he was trying to impress her the whole time which caused him to give his best effort and motivated him to do well. While they were practicing dancing he was constantly making sure he was impressing her and if he messed up he would look to see if she noticed. You can see the effect drive has on Daron as it energizes him in a lot of the things he does when he is around Natalie. You can see it when he goes from not wanting to be at the musical to wanting to be in it as it seemed that drive for being around her gave him the boost in energy to get the part of Romeo.
It was very evident throughout the documentary that testosterone played a large role in the teens bodies. When enough is present it severely increase sexual motivation. It causes an increase in competition and sex drive. It was evident the effect of testosterone on Daron with competition for a woman. When he was in the mall he got in a fight trying to show his dominance over the other guy to Natalie. As soon as they were done tussling and he had shown his dominance over David he directly looked at Natalie and Simone to show them he was the greater man.
The hypothalamus is a critical part in controlling and regulating the desire for a sexual partner. You can see it developing and playing a role in the way Daron is acting. He is unable to control these feelings and they simply happen because of the biological functions.
Natalie uses her behaviors to display her motivation or lack thereof to have Daron be her Romeo. When she walks out she uses her facial expressions and bodily gestures as she finds out. You are able to observe her motivation through these responses and she often expresses her dislike of him when she doesn’t show positive emotions and excitement when she doesn’t have to. Her extent of engagement can easily be seen throughout. She doesn’t pay a lot of attention or interest to Daron and is evident that she is unmotivated because of him. It is also evident though that she is motivated to impress David. She is high energy, intense, and can see her personal investment into him at the beginning and throughout much of the documentary. She shows this as her and Daron were walking to school with each other and then she got the text that Daron was in the playground and took off on a run to find get to him.

After watching Teen Dreams, I found many ways that Darren and Natalie grew and changed because of the hormones in their bodies. Darren was mostly affected by Testosterone, such is known as the “high sexual” motivation. Natalie was more affected by the large amount of Estrogen that is pumping through her body. Estrogen is the female hormone that helps the body develop more female characteristics. When testosterone starts to pump through Darren’s body, he finds himself to be very interested in girls, because of the increased sex drive that testosterone has given him. When he sees girls, such as Natalie, he feels very happy thanks which is caused by a dopamine release. This increase in testosterone makes Darren more competitive, which you can see when he decides to go out for the play in order to catch Natalie's attention. It also makes him aggressive, which is shown when he attacks David at the mall because he made fun of his voice in front of Natalie.
When Testosterone flows through Darren’s body, it goes into the reproductive system, causing him to become “tongue tied” in the presence of Natalie. Darren also finds himself having very sensitive genitals. This can be seen in the video when he is playing in the pool with his friend. He finds himself getting multiple reflex erections a day, more often than just being in the pool. Once Darren’s brain has enough testosterone, it can be converted into estrogen and he can finally begin to grow taller. During this time his skeleton grows faster than ever, making him taller very quickly. This is a problem for Darren because he has not figured out his coordination in this new body. We can see this in the video when they are at play practice and they are all trying to practice a dance. Darren is trying to keep up with the fast paced dance movements but is too uncoordinated. We also see a time when Natalie is affected by testosterone when it comes to boys. It makes her more interested in men because it increases her sex drive like it did to Darren. We see this when she starts to have feelings for David and hangout with him during play practice and outside of school. Natalie is affected by testosterone because it begins to flow into her armpits and groin area to create hair growth.
When Natalie begins to produce large amounts of Estrogen, it has an affect on her emotions. Not only does she produce new emotions, but they become stronger as well. We can see this happening when she tells her parents she wants a tattoo and when they say no she gets very angry and overreacts. She acts this way because she has not yet figured out how to control these new emotions. Once there is not enough Estrogen in her body to combat the Sebum, Natalie starts to develop acne. This decrease in Estrogen in Natalie's body also leads to the cells in her womb to die which leads the layers in her womb to fall off, causing her to start her period. All these changes in the bodies of both Natalie and Darren are because of hormones which come from the brain. This shows just how much goes on in our brains and the importance of these hormones, although uncomfortable at a young age.

Teen dream looks at how the brain works in puberty. This directly relates to Chapter 3 in the book because that was all about the biological factors that happen within your brain. In the chapter it talk about different hormones firing for different reasons and results in your brain. Natalia was going through body changes involving the same two hormones as Darren but they have completely different results.Just like they talked about in the chapter different levels of hormones can do different things as well. Darren, and guys in general, usually have more testosterone than women do and vice versa for estrogen.So the video just walks us through their journeys and the similiarities and the differences between the two.   
When the movie starts they are just two young kids playing together, their motivation for what they are doing is that they are having fun and doing something that they like. Then they start looking at the changes that are starting which begin with gonadotrophin being released from the hypothalamus. It then travels through the body and begins sexual and reproductive function. For For Darren this means that the cells i nhis tsticles are starting to develop and make sperm. The motivation for this is simple in that the body is getting ready to reproduce. The same is true when gonadotrophin releases in Natalia’s bloodstream, developing the ovaries and  preparing the female for menstruation and reproduction. Without realizing that this process is going on, we are being prepared to reproduce, a basic human behavior.
After that step the bodies start to do two different things Darren gets levels of testosterone that drive the urge for sex this is when he starts to notice Natalia in a different way .The video shows his room changing during the nights when his body is starting to change as well, we see it going from posters of fish to posters of women with little clothes on, this is all behaviors that relate to testosterone and the sex drive that he is getting.Along with the behavioral changes he also is physically changing too, with sensitivity to the touch he can get up to 20 erections a day at this point. He starts to break out and his voice drops as well as he is getting taller, which again are all due to a hormone.it is interesting to me that when comparing the two characters Darren started getting blemishes before Natalia but she grew much faster for him. It also was interesting that when either of them does all that growing that you are more likely to fall or be clumsy because your brain can’t keep up with your body. Testosterone is not only creating changes to his body, but also develops extrinsic motivations.He joins clubs and things that he usually wouldn’t do to be around Natalia.He starts to find ways to give into the pleasures and temptations that testosterone is looking for, through sexual things or even aggression.
Natalia is dealing with new levels of estrogen. What happens first is that she loses control of her emotions at first. She doesn’t understand the changes that are happening. . Both will have estrogen and testosterone flow through their bloodstreams. Testosterone causes Natalia’s sex drive to also increase. Once she starts doing that she finds men attractive and starts datign someone just because they are attractive and not because he was nice. I can see the motivation behind this and why in the past it would have been important for survival.Along with that of course she is starting to look for ways to make herself more attractive to males. .

In this movie, Darren and Natalie were a childhood friend. The puberty hit takes place when they are at age of 13. We were able to see how these two individuals change in according to of their behavior, emotion, and motivation. I would say, this movie is closely related to Chapter 3 in our textbook. At age 13, Darren has changed much due to the increasing level of testosterone. There is an act where he is looking around and suddenly spotted Natalie who has a beautiful voice. As we can see there, his pupil is dilating slightly bigger. It is a sign that he is interested in Natalie. The studies suggest that our pupils will dilate slightly bigger than their normal size when we do something we like such as looking at our loved ones, eating our favorite food, watching our favorite movie, looking at our crush, etc. Similarly to something that catches our attention which will cause the dopamines to be released in our brain which it triggers and sends information and finally affect our emotions which it could generate positives or negative emotions. Look at his facial expression. We could see Darren is pretty happy there by having his body lies against the chair he's sitting on and he just enjoyed watching Natalie's singing. Well, that is when his puberty hit. Furthermore, he is impulsively doing something crazy by sneaking around Natalie's house at night. We could say that he is sexually interested in Natalie. This happened due to a high level of testosterone in his body. As in Chapter 3 of our textbook, it states that the high level of testosterone will cause high-level sexual activity. Basically, he is being horny there. This could be proved by the scene when Natalie realizes that there is someone hiding behind the tree. Both of them talking and Natalie showed him where she wants to have tattoos on her body. His facial expression shows that he is somewhat horny. Basically, this is how environment, hormones, and motivation interrelated with each other. Natalie motivates Darren to act crazy and try to be cool which in this context, Natalie is an environmental stimulus to Darren. However, there must be something going on our brain such as the firing of neurons in specific parts of our brain that lead to different behavior presented publicly. Specifically, we could conclude that Natalie, the firing of neurons and the testosterone level motivates him to behave the way he is. There is a scene where he is being jealous when David who is Natalie's boyfriend kissing her at a school. So, he acts slightly aggressive and heading towards his teacher who is obviously sitting in theater's class. This can be concluded that he is pretty bold about what he is doing by asking a position in the '' Romeo and Juliet'' play. Fortunately, he made it. He is really highly motivated to compete with his mate, David. While the second main character, Natalie who is trying to be attractive to catch guy attention. For instance, in the movie, she goes to the mall and trying some perfumes. She smells her hand in trying to decide which one is smell good. By the time, female hormone which is estrogen flows in her blood. So it helps her to make a transformation as a mature woman. She is starting to date a guy. She also finds Darren as an attractive guy even though she already has David as her boyfriend. She is motivated by hormones in her blood. Estrogen is not only helping Natalie to be motivated but also highly emotional by leading her towards rebellious behavior. There is a scene where she is arguing with her parents because she wanted to get a tattoo on her body. Her parents did not allow it because they concerned about her. Parents always do the best to protect their children. She is not capable of understanding it because she needs times to control her emotions. As I watch the entire documentary, the changing phase for a male is quite faster than female. Darren's physical characteristics are mature faster than Natalie, but cognitively, Natalie is more mature compared to Darren.

I could see almost right away that this documentary focuses the most on Chapter 3 of our readings. It goes into specific depths as to how puberty works and how our new hormones can make us do some things that we aren't used to doing. We have no control of our bodies due to us not knowing how to manage the changes that are occurring in our bodies when we become of age. Different hormones will be triggered to motivate a person to do a certain thing. The girl and boy were going through the exact same thing, but the estrogen and testosterone were triggered in different ways and in different amounts. The boy was mostly motivated by his levels of testosterone, while the girl was mostly motivated by her levels of estrogen. For example, the boy got pimples before the girl because his testosterone levels worked quicker in comparison to the girl's estrogen.
We also see that the boy's testosterone is triggered when he sees the girl singing for auditions. She's no longer just a friend to him, he wants to be something more. She on the other hand, is focused on getting the attention of another male who seems to be a bit more developed than the other boy. The boy got jealous because the girl didn't like her and tried out for the play, due to external incentives. The girl's external incentives for trying to be more attractive to the other sex include trying on perfume, makeup, and wanting to get a tattoo.
Not only are these children's motivational brains developing, but so are their emotional brains. For example, the boy gets easily annoyed and aggressive now that his hormones are in full power. He fights with the other boy in the mall after he makes a snide remark. As for the girl, she begins to experience her first menstrual cycle which comes with floods of emotions and dealing with facial acne.
Throughout the whole documentary, us viewers can begin to identify that the motivation and emotion of these two individuals is an affect of their biochemical agents (testosterone and estrogen) being released. It also states that the girl is maturing faster than the boy, but you can also tell from close examination that the boy's physical characteristics mature faster than what the girl's does.

The brain is incredible. It literally controls the entire body. In the documentary Teen Dreams, I was able to see the brains biological functions in action through puberty. Teen Dreams follows well with Chapter 3 and what we have began discussing in class. In Chapter 3, it was made clear that many of our motivations are not always conscious, some come from hormones and natural drives we have as humans. Motivation and emotion starts with our brain, and this documentary was a great example of this biologically.

At the beginning of the film, we see two children, Natalie and Darren, playing. At this point in time, their motivations to interact with each other are strictly to play and have fun. They are children and have yet to experience extreme changes to their hormones, bodies, and brain. These changes will eventually lead to biological, sexual motivators. The film focuses on the children and the transition into the teenage years, where the first stages of puberty begin. Not only do these changes have affects on their bodies, it becomes a large motivator for their behaviors.

The brain is meant to withhold stages of puberty in children until they are ready for it. Once the brain recognizes that it is time for puberty to occur, it begins to release signals throughout the body, telling it that it is ready. In the film, we see that this tends to occur in our sleep, where gonadotropin has begun to produce sex hormones. In Darren, we see the peak in the hormone, testosterone. This begins the stages of puberty for him, starting slowly and silently, but occurring nonetheless.

The blood cells are slowly evolving his testes and reproductive system. In the scene where Darren is waiting for band practice, we are able to see the neurotransmitters from the brain send a signal that was induced by testosterone. This signal alerts him of Natalie, who is trying out for a play. Suddenly, he has this new, sexually driven desire for her.

For Natalie, gonadotropin has produced the hormone estrogen. These new blood cells are slowly evolving her ovaries, until she is able to create an egg. Changes in her body begin to occur, such as a raise in her irritability. This motivates her to argue with her parents more often, which we see in the scene where she talks about wanting to get the tattoo at dinner. She also has become aware of boys in a new way. Early on, we see her spark an interest in David, her cast mate in the play.

At this point, puberty is now in full swing for the both of them. Everyday it gets a little more intense. Natalie and Darren’s bodies begin to grow. Natalie begins to take on the shapes of a woman, while Darren slowly grows in height and his muscles become more obvious. These changes take place in order to make them able to attract a mate. When this becomes too intense, Darren begins to experience acne, as the high levels of testosterone have created high levels of sebum, clogging his pores. He also begins experiencing erections that he has no control over. Eventually, the body produces small levels of estrogen in Darren, which causes the acne to relax more. As for Natalie, her body begins to release small levels of testosterone, which causes her to see acne occur. At this point, more apparent changes begin to take place. Both teens are sexually motivated and the environmental stimulants begin creating more and more changes. Darren becomes more jealous and aggressive, which we see when he fights David over Natalie. Eventually, Natalie’s body is ready for her first period to begin. The egg is not ready, yet. Darren’s cells are quickly multiplying and creating sperm. They are almost to the end of road, wherein they will both be able to reproduce. The body is motivated by this new desire, suddenly sex and attracting a mate has become a biological motivator.

Finally, Natalie and Darren kiss in the play. This moment sparks peak sexual tension. Along with this, Darren can now ejaculate and Natalie’s eggs are ready for reproduction. The brain has completed the body’s reproduction and now they have a new internal motivator, sex and relationships.

After reading chapter 3 and watching the documentary, one can see how the two go hand in hand. While the documentary is focused heavily on reproduction and puberty, the book takes a more in depth look at some of the more specific parts of the brain, as well as the chemical agents that help carry out its orders.
One term that one would hear a lot when watching the documentary is testosterone. One of the main characters in the documentary, Darren, is constantly battling with internal drives caused by testosterone. One of the first times we see it motivating him in the documentary is when he goes to try out for the play. As discussed in class, testosterone is associated with sex drive. Sex drive brings a whole plethora of emotions and feelings along with it. In this particular instance, increasing testosterone levels have caused Darren to feel more competitive, leading him to try out for the play, something he wouldn’t have normally done. Not only is Darren internally motivated by his hormones, he is motivated by external factors, such as Natalie, his love interest. This is a great example that shows how internal and external factors come together to create such a strong motivation and influence ones’ behavior.
Both the book and the documentary focus very heavily one major organ of the body; the brain. Without the brain, not only would we be dead, but we wouldn’t have motivations, emotions, or the ability to control ourselves in any capacity. As it was clearly shown in the movie, the brain controls not only motivations, emotions, and physical changes made to the body but also physical movements. In the film, Darren goes through a growth period which causes him to grow half an inch every month. While this may seem great for an adolescent boy, it will be difficult for him to control his new body as his brain hasn’t adjusted to the change in size. As shown in the dance scene, Darren is not in complete control of his body, causing him to fall. There are other changes that happen to Darrens body that he is not in control of, his voice. As testosterone in his body builds, certain secondary sex characteristics begin to form. The vocal cords in Darrens voice begin to lengthen as his voice begins to deepen. Just like his new bigger body, his brain has a difficult time controlling his voice. We see this in the scene where Darren begins to sing in the play. Everything is fine and Darren is properly controlling his relatively high-pitched voice until his longer, deeper vocal cords kick in and his voice cracks.
This documentary shows how many different things go into motivation and emotion. Take all the functions of the brain and put them into one of the most confusing times in a person’s life and one will see just how intricate the body truly is. It takes a very specific combination of different brain functions, chemicals, and organs to create a functioning human.

In the movie, Teen Dreams, it does an extensive overview of how crucial the role of the brain was in regards to development of the two teens, and the responses their bodies have towards it. The three principles that are discussed in the book are thoroughly intertwined within the characters and scenes. More specifically, the last second principle is shown more within the show.
With biochemical agents, the neurotransmitters in Darren and Natalie’s bodies were sending signals from the brain to the rest of the body to signal development. Another biochemical agent that was used was hormones. As the two developed, their hormones began increasing sending all kinds of messages through the body. Evidences of this were shown in Darren’s body when he began to develop acne, his voice would crack, and he would also produce testosterone, which caused him to suddenly become attracted to his friend.
In certain situations, it was obvious that Darren had a spike in testosterone. He would jump and dance around in his room, kiss the posters of the celebrities on his wall, and feel more confident in his Romeo costume. While all this was going on, his friend next door, Natalie, was facing the highs and lows of hormones. Even though he was over the moon on testosterone, she would be developing as fast, and even faster. However, she would also produce some testosterone, but it wouldn’t provide the same benefit as her friend.
As she matured, Natalie’s body would produce estrogen. In the beginning, the estrogen would help with her complexion, but ultimately, it would have a turn for the worst. Her body began to hit its peak ascension into womanhood when she developed her first period. During this everchanging time, she would have to learn how to deal with her emotions, even though she wasn’t mature enough to control them. When she begins her cycle, she begins to act irritable and unhappy. This is derived from the amygdala which process your harsh emotions such as fear or anger.
In the amygdala, it connects emotion to motivation by responding to a situation that may be threatening. As stated before when Natalie begins her development into womanhood, there were times when she acted irritable. This was because the amygdala was reacting to the threat of her boyfriend offending her, and being mad at her friend. Just as Natalie’s amygdala was reacting, so was Darren’s.
In the mall scene, Darren is walking with his friends and waves at his friend. Immediately, his rival, Natalie’s boyfriend makes fun of him and mocks his high voice. He reacts irrationally, by triggering the amygdala and challenges the boy to a fight. The narrator describes this scene by referencing the prime apes, and how they would challenge another male to win over the female as a partner. Another thing is, when the amygdala is triggered, it causes the body to engage in to the “fight or flight” response, which Darren chose to fight.
While all these developments are going through the bodies of the two teens, it prepares them for sexual activity. However, it will be years before their mind, bodies, and emotions are prepared enough to engage. It is the beginning of the ascension into adulthood.

Chapter three of our textbook explains that the brain is not only a thinking brain but also the center of motivation and emotion. The documentary Teen Dreams perfectly demonstrates this fact. The film uses characters Natalie and Darren to show the changes to the body caused by puberty and, in doing so, provides many great examples of the way in which the brain affects motivation and emotion. All three of the examples I will examine in this post exemplify the three principles of the motivated and emotional brain. The principles state that first, environmental events activate biochemical agents, those agents then stimulate specific brain structures which, in turn, generate motivations.
The first great example of the motivated and emotional brain at work is the activation of Darren's sex drive in the first 7 minutes of the film. As we learned in the textbook, the hypothalamus is responsible for pleasurable feelings associated with important functions like mating. This center of the sex drive is surrounded by the testosterone which seeps from blood vessels in the brain. Testosterone, the biochemical agent in this case, soaks through the membrane of brain cells in the hypothalamus and triggers the chemical reaction of the reproductive circuit which leads to a motivation and drive for sex. When Darren sees Natalie, who he finds attractive, this sex drive increases. This interaction of motivation, brain structures, biochemical agents, and environmental events demonstrates perfectly the three principles. The brain is not cognitively choosing to want sex, it is the work of the motivated brain. This motivation caused by the brain is likely due to the evolutionary importance of mating and reproduction.
A great example of the emotional brain is provided when Natalie begins to experience the mood swings associated with puberty. During puberty Natalie’s body produces estrogen which floods her brain. The estrogen in her brain stimulates nerve endings that were not being used before. At the dinner table, Natalie announces she wants a tattoo and her parents tell her she is not allowed. This unpleasant event along with the large amount of estrogen in Natalie’s brain causes the simulation of new nerve endings. This stimulation of nerve endings triggers a response from brain structures like the amygdala and the hippocampus. As a result Natalie experiences strong negative emotions and becomes defensive and later runs away. No thinking or cognition was involved in these actions. Instead, they demonstrate an emotional reaction and motivation to avoid the situation.
Another example of the motivational and emotional brain is the fight scene at the mall. In this scene, a negative confrontation between David and Darren is the environmental event which triggers a reaction. Increased testosterone levels cause stimulation of brain structures like the amygdala and hippocampus. In this case the “fight or flight” response leads to approach behavior and a fight begins. Emotions of anger and a motivation towards the incentive of victory cause the boys to fight. This is another great demonstration of the three principles at work. These functions occur separately from the thinking brain and are caused instead by the motivated and emotional brain.

The main message in both the book and the video is that the brain is, in fact, the command center that is in control. It is the source of our thinking, motivation and even our growth. One of the main features of the brain is the messages and processes it uses to create a mature human being. That process is known as puberty. Puberty has a lot in store for each and every human as the video, Teen Dreams shows. In some ways it is a lengthy and awkward series of events, and in other ways it happens much quicker than we are prepared for. It even starts in the brain long before its work is shown. Ultimately it is necessary so that we may reproduce and pass along our genes. Puberty revolves around growth and the very powerful motivation to reproduce. The brain is at the center of that desire. Each and every message and hormone is triggered for a reason. And they each come from a specific structure.
The hypothalamus is a major player in this process. Essentially, it’s the hypothalamus that controls puberty. It is responsible for several hormones that aid in the development of teenagers. Primarily this includes gonadotrophins. Testosterone and estrogen are not produced in the brain, but they interact in very important ways with the brain. Each is produced in accordance with the brain's signals in the male and female reproductive organs.
Cells in the brain introduce a chemical in the blood to begin this process. The hormones are called gonadotrophins. They are the signals from the brain, telling the body to begin a transformative process, and to begin producing testosterone in males and estrogen in females. This is the first step in becoming a mature person who is ready to reproduce. And because of this, another process is started, not only the ability to reproduce but the motivation to reproduce.
The textbook refers to our unconscious motives that cause us to act in certain ways. In the movie, Darren is motivated by high testosterone levels to attack David in the mall. Of course, he likely feels he is simply reacting to his emotions, but in reality the testosterone is triggering aggression to perhaps compete for Natalie. This is partially what makes males so aggressive, the nature of testosterone combined with the natural motivation to reproduce.
Another hormone involving a degree of motivation is cortisol, known as the “stress hormone” released from the adrenal gland. In puberty, stress is a certainty. At one point, Darren’s developing body is lengthening his vocal cords rapidly, and his brain has little experience adjusting to the newness of a deeper voice. This leads to an embarrassing voice drop during the play, and leaves him frozen and nervous on stage. The book suggests that cortisol can be released during stressful situations, and Darren is most likely suffering from a mental lapse due to the rise in cortisol levels.
In the end, it’s a challenge for the brain and the body to work in coordination both physically and rationally during puberty. It’s a process that even our brain must become accustomed to. This is because it’s a time of huge changes in motivation due to hormone overload. At one point, Natalie is so overwhelmed by her hormonal changes that she is motivated to become upset with her parents very easily and without great reason. I think that scene along with many others from this movie display the power of our brain.

The movie teen dream focused a lot on the brains biological function which coincided to our chapter 3 reading from our textbook. Just as in our textbook the video focuses on the different areas of the brain and what they are responsible for. A major focus in the video was the prefrontal cortex. It talked about how both Natalie and Daron’s prefrontal cortex was developing and how the prefrontal cortex controls so much of our conscious goals. An example of a conscious goal in the video was when Natalie was trying to get David to notice her. She had a goal that he would notice her so Natalie intentionally did things order for that to happen. Daron increase in aggression is caused by his increase in aggression. His competitive drive is kicking in and when Daron saw Natalie with someone else he became jealous. This arousal in his sex organs is causing him to do something he normally wouldn’t do. The changing they are going through are helping prepare their bodies for mating. Our bodies and brains work together to prepare us for our physical, mental, and emotional prime.
Another focus of the movie that has also been a focus in our textbook is what causes motivation. In the case of the video the cause of the change is an increase in sex hormones. Our sex hormones change our intuition, persistence, change, goal directions, and stabilization. The two sex hormones discussed were estrogen and testosterone. The main characters Natalie and Daron both demonstrated how their sex hormones were increasing as they are growing up. When Natalie and Daron first come on as children the video discusses how our brain is. It is interesting to see how their biological function changes as they grow up.
Another major focus in our class is emotion which is not surprising because our class is called motivation and emotion. Our emotion a big impact on how motivated we are to do something. Connecting that to the video it is evident to see that Daron’s physiological preparedness drives his body to look for a mate. From an early age our body is forced to meet situational demands. Motives also have a large impact on what we do and why we do it. Internal motive when Daron waited for Natalie to leave her house before he left his but Natalie had an external motivation to leave her house because she wanted to go meet up with her friends
Our brain stimulates our body to do everything. In the movie, it stimulates Natalie and Daron’s body to grow at night. It also stimulates Natalie’s brain to have a monthly period cycle. In the book, it discusses how our brain is activated to help us survive. Our brain works with our nervous and endocrine systems while adding in chemical substances to make it happen. It is very interesting to see how all of it comes together to keep us surviving and thriving.

In the documentary “Teen Dreams” it looks at puberty in adolescence. From what we have read, this is closely related to chapter 3 covering “The brain”. The show follows two main characters throughout their puberty to see how both male and females react, but more importantly how the body reacts to what is going on with their hormones. The male character, Darren begins to go through puberty lead by the hormone testosterone. The female character, Natalie is also going through puberty, but instead estrogen is the hormone that is being spread throughout her body. This does not mean that a female won’t have testosterone and a male won’t have estrogen, this just shows that the hormone isn’t as big of a presence. Over time a male will start to convert the testosterone into estrogen to start their growth spurt, but this usually happens later than most women due to women producing estrogen as their primary hormone. This growth spurt is the reason for the bones lengthening which results in kids getting taller around this period.
In chapter 3 it talks about how hormones and neurotransmitters both play a major role in motivation. In the case of testosterone, the hormone is associated with having sexual motivation. Testosterone is the primary hormone responsible for looking for a mate and also the competitive nature that comes with that between men. With this hormone also comes an increase in muscle mass due to the testosterone increasing and stretching out the muscle fibers in their body.
In the documentary it shows one of the downsides to producing these hormones. While both male and females get pimples, they are slightly more common in men due to the estrogen produced in females keeping the levels of sebum down. This later affects females when their estrogen levels lower and are not able to keep the sebum levels down.
In many of these biological occurrences, it is often viewed as a primal instinct. These hormones and changes were needed to survive and thrive in reproducing and finding a mate. Along with the changes I mentioned there are also changes in voice, body hair and odor, and lack of coordination. These changes occurring all around the same time are what makes a young adult often seen as so awkward because they don’t know how to handle these changes going on. These hormones greatly affect what it is we are now motivated by. With the onset of puberty we are now motivated by many new things. These things may even tie in with one another, for example lifting to get and look stronger to get girls attention with the underlying goal of mating with them.
Everyone who has been through puberty knows what it all entails, but not everyone may have known how or why these changes happened. This documentary shows us how these hormones can cause us to be motivated doing certain things. It also shows us how the brain is the one that is in charge of these changes and really everything that happens in our body. Motivation seems to be the main thing covered in the textbook, but I think this documentary does a good job of showing what the emotions behind certain acts may be.

Terms: Hormones, testosterone, estrogen, and primal instinct.

This documentary relates very closely to the subject matters of chapter three in our textbook; The Motivated and Emotional Brain. As we’ve learned these past few weeks, our brain plays a huge role when it comes to our motivations, emotions and behaviors. This documentary shows us how the brain also plays a huge role in our physical and psychological development, specifically through puberty in the life of two teenagers, Natalie and Darren.
Darren and Natalie both go through a lot of changes in their brain and body throughout this documentary. One of the first things to happen in Darren’s brain is that a group of cells are activated causing a release of hormones carrying signals, which helps cells divide and then form into tubes. The forming of these tubes causes changes in his testicles, which triggers the production of testosterone, a key sex hormone that regulates the functions of numerous things such as Darren’s sex drive, muscle mass and functioning, production of sperm, etc. This increase in for instance sex drive makes it difficult for Darren to focus while trying to have a conversation with Natalie when he unexpectedly meets her in the backyard. This is due to an interference from his reproductive organs. He has now gotten to a point where he is sort of losing control over his emotions, and he can’t control his mind.
At the same time, Natalie’s body starts to produce gonadotropin, which triggers the production of the female sex hormone estrogen. The increase in the production of estrogen makes in-active areas of Natalie’s brain come to life, and fires new powerful emotions, making her experience very strong feelings as well. These hormones are causing Natalie to feel a lot of anger and frustration, and are motivating her rebellious behavior, especially towards her parents. Around the dinner table she tells her parents she is getting a tattoo, and she gets very upset when that request or statement is declined and shut down by her parents.
With Natalie’s puberty comes an increase in hair growth and body odor, which is an outward sign of maturity. When practicing their acting for Romeo and Juliet, Darren’s limbic system receives a sensory stimulation of smell, that being Natalie’s body odor, and it causes an automatic emotional reaction in him. He is instantly turned off by her body odor and only gives her a short kiss on the cheek instead of a real good one on the lips.
When Darren gets ready to sing in the school play, he experiences a change in his vocal cords. Since his body is growing and maturing, his vocal cords are also changing, which makes his voice break. This motivates Darren to not sing as he can’t trust his own voice to sound good for the play.
It’s difficult to grasp what exactly motivates our behaviors, but these first three chapters have really helped me personally understand the biological changes we go through that are key concepts when it comes to our motivations and emotions.

After watching “Teen Dreams”, I found the information within the text and documentary segments to relate more to real life situations as an individual rather than in the film. It was fascinating point of view to see the biological changes when we ourselves may not have even been aware of when we went through the whirlwind of transformations during puberty. Figure 3.3 in the text was also quite useful throughout the documentary to explain the hormonal and motivational changes for both Natalie and Darren. Both experienced multiple environmental events that lead to a biochemical agent being released that signaled activity in a brain structure creating the almost always unintended emotion.
The scene of Darren and Natalie playing as children is important because their motivation for interaction is not based on sexual desire, but rather the intended feeling of having fun from playing. However, Darren will be the first to experience the puberty changes while sleeping. This is a biological change that not many would guess would occur in sleep or for how long it actually takes. Darren’s brain releases indications that his body is ready to being the maturation process by releasing gonadotropins. Once his reproductive system has begun its awakening, testosterone began to take over his body. What is also fascinating is that estrogen is also slowing being produced within Darren’s body, which will ultimately result in his growth spurt.
Natalie began her puberty phase later than Darren but still when through biological changes in her sleep over a few years time too. One of the evident changes both in the documentary and in real life is the change in emotional awareness. Natalie’s mood was one of the first major changes in her maturation, which can be seen when she is arguing with her father about perfume and a tattoo. What seems like a potentially civil conversation was taken to a level of defensiveness because Natalie was experiencing a rise in testosterone levels. These levels are what will begin Natalie’s sexual drives. Natalie is also the first to experience growth changes because of the estrogen production throughout her body. She becomes taller than Darren and also begins developing breasts, but did not reach the level of sexual desire as Darren.
Darren testosterone-filled body craved sexual activity, therefore whenever he saw something sexually pleasing his brain would release dopamine. Because he is motivated to mate, his dopamine release creates a response in which his body needs to prepare for which resulted in an erection. His testosterone level also lead to more aggressive behavior, which the mall scene can be used as an example. His testosterone levels increased the level of anger he had already generated within his amygdala after being made fun off, so he defended himself by physically fighting back.


The biology of the reproductive system in both male and females are highly integrated with the emotional and motivated parts of the brain.  The motivation or drive to have sex doesn't develop within the human body until we reach pueberty.  Once peuberty is reached- different hormones are developed and released into the bloodstream in the male and female body.  Within the male body, once puberty is taking its process - the cells in the testicles divide and and ganatrophins trigger celss to make testosrtone, whcih is the sex driving hormone.  At this point in puberty for males they can reproduce, but the WANT to in the brain has to mature still.  This can relate to the drive in approach motivation/behavior to have the courage to go up to females and share a relationship with them or not.  This can also relate to the like and want operation of dopamine. He may like her, but not want to have sex quite yet. While males are going through this confusing sex drive, the reproductive system distracts the brain in maintaining  the appropriate social interactions with the other sex; motivating the male to avoidance of interactions and being tongue tied when the he is overwhelmed with hormones; specifically testosterones. This relates to the avoidance generated structures of the brain. The want for sex isn't developed until their sperm is no longer dormant, and the overflow of testosterone creates estrogen to balance out the male hormones. Once then, the want becomes strong. While dealing with all these hormones, specific behaviors are motivated to come about. For example, the wiring off the circuits for both aggression and sex overlap in males. Causing the male to fight for the opposite sex, which was the way our ancestors conquered their mate.
During the puberty of females, the gonadotropins bring ovaries to life.  There is now a new hormone, estrogen, which is another sex hormone.  Felmales seem to mature faster than males. While dealing with all these hormones, females aren't experts quite yet at controlling them. This may cause them to behave impulsively. When women are have reached the end of puberty, she starts her period. In her womb, cells making up lining die, and sheer off. Her period does not start because she is ready to reproduce, but the brain is locked into a monthly cycle. Once she is able to reproduce, that one perfect egg is developed and she is fertile, that egg is released in her period. This can account for the reason why women tend to want sex less than men, females have to invest more in reproducing (bearing children). Females tend to find one best candidate, while in men's nature they that desire for ONE mate isn't as strong.
All the human anatomy, the biochemical agents, and brain structures in the process of puberty relate to the motivated and emotional brain. One example can be, an environmental event like Darren and Dan at the mall when they see their crush. Both of them released dopamine and their testosterone began to play a heavy role when they knew they had to compete and become aggressive to each other to win her. These biochemical agents were released into the hypothalamus. Which created this aroused motivation of aggression, which motivated them to fight each other.
