AR-News: (AU) Study uncovers unique quality of primate brains

[Animalara2003 at aol.com]

A study of the brains of primates ranging from tiny bush babies to humans and 
apes shows that size really may matter, researchers said. 
All primates have an unusually large frontal cortex, a part of the brain used 
by humans for higher thought and reasoning, they found. 
>From lemurs to chimpanzees, that part of the brain is especially large 
compared with overall brain size, the California Institute of Technology team in the 
US found. 
"In primates, having a bigger brain means you have a disproportionately 
larger frontal cortex," Eliot Bush said, a PhD candidate at Caltech who worked on 
the study.
