The teenage Brain

Teenagers have big brainsScientists used to believe that our brains were fully developed by early childhood. New researchshows that the brain grows very quickly between the ages of 10 and 12, when it is at its biggest.During the teenage years your brain shrinks bit by bit until it is the size of an average adult's.

Explaining Teenage Behaviour The frontal and parietal lobes are the last to finish developing. The frontal and parietal lobes manage judgement, reasoning, planning for the future and visual/spatial \ability. This may explain why teenagers are sometimes more impulsive, emotional and clumsy than adults. It's not your fault, your brain's too big!

Building a better brain The teenage years are an important time in your brain's development and you can build a better brain. The activities of the teenager influence which cellsdisappear and which cells remain as they get older. Dr Giedd, a psychiatrist, says, "If you're lying on the sofa or playing video games your brain gets programmed for that." His advice: Test your brain. "If you exercise a muscle, you make it stronger. The brain works like that. Try a foreign language, music, games - anything that makes the brain work hard." How you're using your brain now, influences the kind of brain you have when you're an adult. Don't say we didn't warn you!
