Have you ever wondered where “intelligence” lives in the brain? Many have, including scientists at the University of Illinois, who have been working to map the physical architecture of intelligence in the brain. They discovered that several regions in the brain, along with the connections between them, were most important for general intelligence. These regions included:
· The left prefrontal cortex (behind the forehead)
· The left temporal cortex (behind the ear)
· The left parietal cortex (at the top rear of the head)
· The “white matter association tracts” that connect these regions.
According to Aron Barbrey, Professor of Neuroscience, the study showed that intelligence depends not on one brain region or even the brain as a whole, but involves specific brain areas working together in a coordinated fashion.
