Researchers identify language feature unique to human brain
This story is from the category The Brain
Date posted: 24/03/2008
Researchers at Emory University have identified a language feature unique to the human brain that is shedding light on how human language evolved. The study marks the first use of diffusion tensor imaging (DTI), a non-invasive imaging technique, to compare human brain structures to those of chimpanzees, our closest living relative.
The researchers compared the arcuate fasciculus, a pathway that connects brain regions known to be involved in language in humans, rhesus macaques and chimpanzees. The human arcuate fasiculus was much larger and more widespread.
