Brain Development And Adulthood

The court said that because of their youth, their brains are less developed, they are more impulsive, more subject to peer pressure and less able to see the consequences of their actions. Researchers have started to look into the development of the brain from the ages of 3 to 20 years old. Brain research by Thompson and others suggests that teenagers are unformed, less mature and less resistant to peer pressure than adults are. According to Thompson’s research, “gray matter, which brain researchers believe supports all our thinking and emotions, is purged at a rate of 1 percent to 2 percent a year” (89). He also states that, “these frontal lobes, which inhibit our violent passions, rash actions, and regulate our emotions, are vastly immature throughout the teenage years” (89). Teens do know what they have done and they are capable of understanding right from wrong but their brains aren’t developed enough to make fully mature decisions.

The article “Dude, Where’s My Frontal Cortex?” by Robert Sapolsky talks about the delayed maturation of the frontal cortex in teenagers and how the underdeveloped frontal cortex is the cause of erratic behavior of teenagers. Sapolsky explains to the reader how the frontal cortex does not fully develop until the age of twenty for a person and how that part of the brain is important for extensive reasoning, impulse control, and emotional regulation. He shows the reader how particularly emotional situations affect both a teenager and an adult differently due to either having or not having a matured frontal cortex. This example that he uses allows for the reader to see how a teenager responds to situations with extreme thoughts and behavior which

David Dobbs in the Article “Beautiful Brains” proves the theme that it takes teenage brains longer to mature due to the recent change in impulsivity and adolescent behaviors.

Research studies have been conducted to demonstrate that adolescent brains are without full adult potential thus, adolescents should not be charged with adult sentences for crimes committed under the age of 18. Several doctors note that the under development of the brain, though it does not excuse criminal behavior, should not result in a life sentence or any other irreversible or extreme punishment (Beckman, 2004, p. 1). Beckman (2004) also states that “eight medical and mental health organizations, including the American Medical Association cite a sheaf of developmental

The author of the article states that there is no better time than now to review how we are raising teenagers for many reasons. First and foremost there have been many strides taken recently to understand how the adolescent brain develops, strengthening ones understanding, and in turn, shedding light on errors made in the way adolescents are being raised in relation to their neuro-development. This means that because scientists have learned substantial information about the brain recently, it is important to reevaluate how parents are raising teenagers now more than ever. Second, according to the article it is a good time to review how we are raising teenagers because children are becoming adolescents earlier based on their physical maturation increasing faster each year, therefore it is important to examine why this is occurring. Finally, the author states that there is no better time to review how we are raising teenagers because of the recent discovery that the brain is malleable during adolescence due to neuroplasticity, meaning that the brain is able to be transformed during this time period solely based on the environment in which these individuals are exposed to, as per the article (Steinberg, 2014).

This essay is going to list and compare adult and adolescent behaviour, characteristics and try to analyse how certain adolescent characteristics change into adulthood. It will look at what characteristics change and what don’t, look up the information to do with the question and rewrite the information without changing the meaning and make sure it will have the source links at the bottom of the essay. It will show images of the brain at different ages. It will show; development of the brain, consequences of adolescence for example drink driving, what is fMRI, sMRI, PET and EEG.

When one compares the structure of the adult brain and the teenage brain, there will be several differences between the two. Adults have stronger connections from one nerve cell to another, and they all have essential communication skills. However, teenagers have more synapses and have weaker nerve connections. Also, their frontal lobes aren 't fully developed. This causes adolescence to have impulsive behavior and they typically do not recognize consequences in a situation. In the early twenties the brain becomes fully developed, so people are very good at making decision and they are able to think abstractly. There are many factors that contribute to the construction of the brain; some things help the brain develop normally, other things interrupt the process. There is a substantial amount of distinctions between the adult brain and the adolescent brain, and these includes behavioral and structural differences.

Are you under 25? If you are, how well do you think your brain is developed? In the video “The Teen Brain: Under Construction” claims that the brain is finished developing around the age of 25. This assertion starts many arguments on whether an 18 year olds should be considered an adult. Many say that 18 year olds should be considered adults, but many disagree. I deem that 18 year olds should not be considered adults, because their brains are not fully developed yet.

The prefrontal cortex, which is the anterior part of the frontal lobes, controls understanding consequences, impulse control, abstract thinking, long range planning, and mental flexibility (Ortiz 93-94). Researchers at UCLA, Harvard Medical School, and the National Institute of Health have been working together to understand brain development. Their research has shown that at a young age the brain overproduces gray matter, which is the overall thinking part of the brain. After this comes the pruning process in which gray matter is removed. Paul Thompson from UCLA describes this time as a "massive loss of brain tissue" (as quoted in Ortiz 94). The average amount of tissue lost per year is one to two percent (Ortiz 94). While this pruning process is taking place the myelination is occurring simultaneously. Myelination is when white matter, what insulates the brain, makes brain process more efficient. This process is also thought to shape brains neural connections for adulthood (Ortiz 95). With age, the brain becomes denser and more organized which makes it better at processing and understanding information. Changes in the brain also can happen late into the twenty's (Beckman 3). A member of the UCLA research team reported that "[The] frontal lobe undergoes the most change during adolescence-by far. It is also the last part of the brain development" (as quoted in Ortiz 94). For most, full brain development is reached during the ages

Based upon scientific findings, the adolescent brain is constantly growing and changing. The character Romeo, in Shakespeare’s famous play, displays how his adolescent brain is growing and changing. For instance, in the play, it states,”She is too fair, too wise, wisely too fair, to merit bliss by making me more despair.” (1.1. 218-219) This quote reveals that Romeo is deeply in love with Rosaline but as his youthful brain changes he quickly falls in love with Juliet with little knowledge of her. Not to mention, in the article, Are teenage brains really different from adult brains, it conveys, “Teenagers experience a wealth of growth in synapses during adolescence” (Edmonds). This small excerpt informs us that the synapses that help us make reasonable decisions are at an increase. In the same source, another significant

The teenage brain is different from the adult brain version because it is not fully developed. The part of the brain used for emotions like rage and fright, the amygdala is much more developed than the frontal cortex (used for thinking through your thoughts). The way scientists found this out was pictures of Teen’s brains in action. (Teen Brain…). This would explain why teens tend to be more angry and impulsive compared to adults. Teens have a higher chance of impulsive acting, starting fights, do risky behaviors, etc. Knowledge of the teen’s frontal cortex’s lack of development can assist guardians, teachers, and lawmakers in unlocking the answers on management on how to manage adolescent behavior.

As adults age their executive functioning start to slow down. The structural changes in the prefrontal cortex

Elderly people physically slow down and have lower energy levels. There are changes in the body systems and organs that can usually result in all types of

Why does the human brain age? Brain aging is a part of human life and a big part of society as the awareness for brain aging increases. Over time memory tends to become less efficient as we age and the neurons in the brain decreases (Bendheim, P.E. (2009). By 2050 in the US, 20 percent of the population will be 65 years or older. And as the elderly population increases, so will the incidence of age-related neurological disorders (Perlmutter, David. (2004). Therefor it is important to understand the aging brain, and how to keep the brain functioning as one ages.

Brain development in the first two years is the most important and critical. Maria Montessori referred to this time as of the "absorbent mind" Early brain development is the frame work for the road ahead. When and how the brain develops in the first two years will play a critical role into adulthood. At birth, the brain is the only incomplete organ. The brain will continue to grow through childhood and adolescents.
