"The brain absolutely has rhythm," says <a href="http://www.cmu.edu/bio/faculty/urban.html">Nathan Urban</a>, a neuroscientist at Carnegie Mellon University in Pittsburgh.<p>When you concentrate, Urban says, your brain produces rapid, rhythmic electrical impulses called gamma waves. When you relax, it generates much slower alpha waves.<p>The internal cadences of the brain and nervous system appear to play an important role in everything from walking to thinking, Urban says.
