Jon Hamilton en Your Brain's Got Rhythm, And Syncs When You Think Even if you can't keep a beat, your brain can. "The brain absolutely has rhythm," says <a href="">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.

That has led to an experimental drug for the disease that's based on a hormone associated with pregnancy.<p>The hormone is a form of estrogen called estriol. It's abundant in a woman's body only when she is pregnant.

In fact, people with lots of education are seven times more likely than high school dropouts to have no measurable disability a year later.<p>"It's a very dramatic difference," says <a href="">Eric Schneider</a>, an epidemiologist at Johns Hopkins and the lead author of a new study.

The only exception to the helmet rule was for students who received an award.<p>"The big deal for them is that they can take the helmet off while they're walking across the stage," Soltesz says.
