Intelligence in humans is fundamentally social.

University of Illinois neuroscience professor Aron Barbey and his colleagues found that brain regions that contribute to social problem solving also play a role in general intelligence.Aron Barbey
Vietnam veterans who received penetrating head wounds during combat are helping to unlock some of the deepest mysteries of the brain. Scientists at the University of Illinois Urbana-Champaign studied 144 veterans who received penetrating head wounds from shrapnel or bullets, which damaged specific areas of the brain while leaving nearby regions intact. The researchers mapped each vet's brain with CT scans and then combined all of the scans to create a detailed map of the brain. They also administered a detailed battery of tests measuring social, emotional, and cognitive functioning. In a new study published in the journal Brain, the scientists showed that the regions implicated in social functioning had a significant overlap with the regions that were key to emotional and general intelligence. The researchers say that these results support the idea that intelligence in humans is fundamentally social.Vietnam veterans who received penetrating head wounds during combat are helping to unlock some of the deepest mysteries of the brain.
