Eyes Do Math

Researchers scanned brain activity of people moving their eyes right or left and asked participants to do mental math. They found that the brain circuitry that moves the eyes right does mental addition and the circuitry moving eyes left does mental subtraction. The finding demonstrates that math's development is too recent and advanced to have a brain region solely devoted to it - we reuse preexisting systems.
