The bad news: teenagers' brains are underdeveloped. The good news: you can turn your mind into a machine which is quick and bright!The teenage brain, according to the latest research, is different from the adult brain. ¡t's less developed and more changeable than scientists had previously thought. This has led some researchersto an amazing conclusion: teenagers can influence how their own brains develop. As a result, the way you spend your time determines how much brain power you will eventually have when you grow up. Youcan actually increase your brain power!
Mental Growth Spurts
Until recently, scientists believed that the human brain reaches maturity at puberty. However, now they think the teenage brain is a workin progress and for this reason, the teenage years are a critical time in brain development.
The parts of the brain which are not used die off. They are cut off-or "pruned," as scientists describecell death-, and the brain rewires itself. Until their brains are totally pruned, teenagers don't have full use of some of its most vital and sophisticated parts, including the areasinvolved injudgment, reasoning and planning for the future. These areas are not completely "online" until the late teens. This does not mean that teenagers are stupid, but until the judgment and reasoning centers arefully mature, teenage behavior may be more driven by instinct and immediate gratification.
Building a Better Brain
There is also good news. The "un-pruned" nature of the teenage brain-which may maketeenagers impulsive-is the very thing that gives teenagers the ability to control their brain's development.
According to the scientists, which cells are pruned and which remain is determined largelyby the person's activities. Teenagers' activities hardwire their brains for the rest of their lives. If you exercise a muscle, you make ít stronger; consequently, the more you deal with difficult...
