Charting Brain Growth in Humans and Chimps, Kyoto University Study  
8/24/2011 7:13:05 AM

Although baby humans and baby chimpanzees both start out with undeveloped forebrains, a new study reports that the human brain increases in volume much more rapidly early on. The growth is in a region of the brain known as the prefrontal cortex and is part of what makes humans cognitively advanced compared with other animals, including the chimpanzee, our closest relative. The prefrontal cortex plays a major role in decision-making, self-awareness and creative thinking.
