In an age of multi-tasking, experts say the brain still needs down time. Angelika Dimoka, director of the Center for Neural Decision Making at Temple's Fox School of Business, studies how the brain processes information. Her research has found that, as the flow of information increases, activity increases in the region of the brain responsible for decisions and control of emotions — but only up to a point. Flood the brain with too much information, and activity in this region suddenly drops off. This center for smart thinking not only doesn't increase its performance, it checks out.
