Live from GSE: National Geographic on Teenage Brains

Live from GSE, our Student Ambassador, Seth, a current student in the Counseling and Personnel Services (School Counseling) program, has suggested an article from National Geographic entitled “Teenage Brains” by David Dobbs.

“Although you know your teenager takes some chances, it can be a shock to hear about them.  One fine May morning not long ago my oldest son, 17 at the time, phoned to tell me that he had just spent a couple hours at the state police barracks.  Apparently he had been driving ‘a little fast.’  What, I asked, was ‘a little fast?’  Turns out the product of my genes and loving care, the boy-man I had swaddled, coddled, cooed at, and then pushed and pulled to the brink of manhood, had been flying down the highway at 113 miles an hour.  ‘That’s more than a little fast,’ I said.”

The first full series of scans of the developing adolescent brain- a National Institute of Health (NIH) project that studied over a hundred young people as they grew up during the 1990s- showed that our brains undergo a massive reorganization between our 12th and 25th years.  The brain doesn’t actually grow very much during this period.  It has already reached 90 percent of its full size by the time a person is six, and a thickening skull accounts for most head growth afterward.  But as we move through adolescence, the brain undergoes extensive remodeling, resembling a network and wiring upgrade.”
