What is The Vestibular-Optokinetic System about?

This chapter reviews properties and neural substrate of vestibular and optokinetic eye movements. Geometric aspects of head rotations and translations (linear movements) are related to properties of rotational and translational vestibulo-ocular reflexes. The motion sensors of the vestibular labyrinth -the semicircular canals and otolith organs - are described. The contributions that direct and indirect central pathways make to the direction and temporal properties of vestibulo-ocular responses are summarized. Optokinetic-vestibular interactions during sustained rotations are discussed. Properties of vestibular and optokinetic responses -gain, phase, and time constant - are explained as well as how they are influenced by factors including target location, mental set, and changing visual demands (vestibular adaptation and the cerebellum). The multiple cerebral areas that contribute to vestibular sensation are reviewed. Clinical and laboratory evaluation of vestibulo-ocular function is summarized including rotational and caloric testing, and vestibular-evoked myogenic potentials (VEMPs). The pathogenesis of common vestibular and optokinetic disorders is reviewed.
