Description

Scientists have long known that the brain's gray matter decreases in volume during adolescence. This even though mental performance improves dramatically from childhood to young adulthood.Gray matter is the tissue in brain areas involved in seeing and hearing, memory, speech, emotions, decision making and self-control.It shrinks in volume during adolescence. But a new University of Pennsylvania study finds it becomes more dense to compensate.Girls may have lower brain volume than boys, proportionate to their smaller size. But their gray matter is more dense. Researchers said that may be why their mental skills are comparable.http://www.upi.com/Health_News/2017/0...http://www.wochit.comThis video was produced by YT Wochit News using http://wochit.com
