Abstract
The vestibulo-ocular reflexes (VORs) serve to keep our image of the world stable as we move. This is accomplished by using signals about head motion from the vestibular apparatus of the inner ear to produce compensatory eye movements that are equal in amplitude and opposite in direction. The semicircular canals detect head rotations, whereas the otolith organs detect head translations and re-orientations relative to gravity. The system is remarkably plastic and can quickly learn to change its output under different sensory and motor conditions. The simplicity and flexibility of the VOR have made it an ideal sensorimotor system to study.
