Abstract
The vestibular system contributes to the generation of conjugate eye movements, spatial orientation, and postural control. The functional connections of the vestibular end-organs and of the descending vestibulospinal pathways and their importance to postural control were reviewed in the previous paper by Keshner and Cohen (pp. 320–330). This paper reviews the ascending vestibular pathways, the visual/vestibular interactions, and the role of the vestibular system in oculomotor control and spatial orientation.
