Mapping Intelligence in the Brain

A new study by University of Illinois neuroscience professor, Aaron Barbey, has enlisted 182 veterans with brain injury to explore the connections and roles between different parts of injured and non-injured brain.

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

In fact, the particular regions and connections we found support an emerging body of neuroscience evidence indicating that intelligence depends on the brain's ability to integrate information from verbal, visual, spatial and executive processes. [These findings will] open the door to further investigations into the biological basis of intelligence, exploring how the brain, genes, nutrition and the environment together interact to shape the development and continued evolution of the remarkable intellectual abilities that make us human."
