Aggression in boys linked to enlarged brain region

Aggression in some teenaged boys may be linked to overly large amygdalas. That's a region in the brain involved in emotion and other functions.

An article in the proceedings of the National Academy of Science reports that these boys may also be unable to control their emotions because other parts of the brain that normally control strong emotions don't mature until the early 20s.

Researchers say it's important for parents to bear in mind that, while their teenage child looks like an adult and does very complicated work at school, parts of their brain are still developing really until the 20s.
