Should we throw a 13 year old in prison because of something he did when he was a teenager? Science says brain development has evidence that teenagers should be given a little leeway. The brain is not fully developed until adulthood. In the article “The Teenage Brain: It's Not Grown Up Yet,” written by Richard Knox, we read, “The nerve cells that connect teenagers' frontal lobes with the rest of their brains are slow.” The adolescent brain is also reactive to everything around it. Whatever a teenager does, the brain responds in various ways. In the article “The Adolescent Brain: Behavior, Problem Solving, and Decision Making,” it says “The Amugdala, which is responsible for instinctive reactions including fear and aggressive behavior, ………………..” The Teens may make not very intelligent decisions, but it might be due to the way teen brains develop. The brain develops over many years. Therefore teenagers make irresponsible decisions. The protagonist of the novel "The Adoration of Jenna Fox", by Mary E. Pearson, is a normal teenager. One day Jenna was with her friends doing things that teenagers would normally do. Things like partying. And obviously where there's a party, there's also alcohol. So Jenna and her friends were just trying to have fun and started drinking. Perhaps because her prefrontal cortex wasn't developed, Jenna and her friends didn't think drinking was a good idea since they had to drive home. In the book, Jenna explained to her mother that the reason she went into a coma was because she was in an accident. Jenna said: “I was crossing the stream. I stepped on the first stone. And then…” The frontal lobes of the brain don't connect until adulthood. That's the part of the brain that... middle of paper... others didn't like. Jenna didn't even know if this was her real family and she had wondered sometimes. As he watched the videos he started to remember things. In the book Jenna says: “There are many words and definitions that I have never lost. But some I'm just starting to really understand. This shows that the brain can develop in mysterious ways. I believe that because of the way adolescent brains develop, this allowed Jenna to only remember some things and not all. If she had been an adult perhaps she would have known something about it. I know he had to rebuild his entire brain on a hard drive and learn everything from scratch, but obviously he didn't have to learn everything from scratch because he still knew how to talk and remembered some things. Scientists are trying to understand why the brain does this. However they understood most of the problem.
