  • Researchers use brain-injury data to map intelligence in the brain

    University of Illinois neuroscience professor Aron Barbey led a study that mapped the brain regions essential to intelligence and to executive function (the ability to plan, organize and regulate behavior).

      In a video, Aron Barbey discusses his work linking specific brain injuries, seen here in a brain scan, to impairment on particular cognitive functions.

      A new study found that specific structures, primarily on the left side of the brain, are vital to general intelligence and executive function (the ability to regulate and control behavior). Brain regions that are associated with general intelligence and executive function are shown in color, with red indicating common areas, orange indicating regions specific to general intelligence, and yellow indicating areas specific to executive function.
