Teenagers are often thought of as irresponsible — or even reckless. But a group of local researchers recently came to a different conclusion about what's going on in the teenage brain.
Stereotypes about young people and their brains abound, and scientists have not been immune to those ideas, said Dan Romer, research director at the University of Pennsylvania's Annenberg Public Policy Center.
First, it was raging hormones that explained those wacky teens. Then, Romer said, it was the fact that the prefrontal cortex doesn't fully develop until adulthood.
