Whos Got Rhythm? Your Brain Does

In an attempt to understand what makes us tick, researchers have been probing various regions of the brain, such as the premotor cortex, which helps make movement possible, and the auditory cortex, responsible for processing what we hear. But neuroscientists now say communication between regions—as opposed to within the areas themselves—may be the key that has eluded analysis until now, in part, because of technological obstacles.
