If you are a parent of a teen going through puberty you will know all about the hormonal changes they go through. Now, a Georgia State University scientist has found that those hormones in males may be key to changes in a part of the brain responsible for social behaviors.
It will take some time for those teen brains to develop fully though, as we know now from new research that the brain continues to develop after childhood and puberty, and is not fully developed until people are well into their 30s and 40s. The findings contradict current theories that the brain matures much earlier.
And still on the subject of teenagers, PBS science correspondent, Miles O’Brien looks at what could be happening to teenage brains as they develop in a rapid-fire world of technology and gadgets.
