Brain Injury Study Unlocks Science Of Intelligence

Science Daily reported on a study of Vietnam veterans with brain injuries and the results seem to have unlocked some of the keys to intelligence, as they related to the structure of the brain.

“We found that general intelligence depends on a remarkably circumscribed neural system,” Barbey said. “Several brain regions, and the connections between them, were most important for general intelligence.”

These structures are located primarily within the left prefrontal cortex (behind the forehead), left temporal cortex (behind the ear) and left parietal cortex (at the top rear of the head) and in “white matter association tracts” that connect them.

Definitely click though above. It’s very interesting stuff.
