It takes brains to be good at math - as in, two halves of one brain, working together. That's the conclusion of Joonkoo Park, a postdoctoral fellow in Duke's Center for Cognitive Neuroscience, who led a study linking communication between the left and right halves of the brain to mathematical ability. Park had subjects perform simple math problems while he studied images of activity in their brains. Those with especially chatty brains - where crosstalk flowed freely between left and right hemispheres - solved the problems faster. The finding may lead to new treatments for cognitive problems related to math.
