The body's interval timer—a short-term timepiece separate from the better known circadian clock—used to be viewed as something close to a myth, but the neurobiological evidence is getting hard to ignore. This week, at the annual meeting of the American Association for the Advancement of Science, researchers detailed some of the clock's neural circuits, showed how disrupting them disrupts a sense of time in people and in animals, and how Parkinson's disease fouls the clock's gears.
