Getting Your Bearings
Losing your balance and feeling dizzy? It happens when the body is in motion, and to some people, when they age. Now scientists are trying to figure out why. What disturbs the body's equilibrium and brings on seasickness or motion sickness? Some of the problems of balance here on Earth -- like spatial disorientation and nausea -- are experienced by astronauts in outer space as well as by Earth-bound people as they age. "Getting Your Bearings" explores the body's complex neurovestibular system that controls our ability to balance and to adapt to shifts in orientation and environment.RealMedia's free RealPlayer is needed to listen to this clip.
