The otologist's ability to interpret vestibular movements of the eyes is directly related to his understanding of the various neural mechanisms responsible for ocular movements. As Gordon Holmes1 has pointed out, in man vision is exclusively a cortical phenomenon, and the cortex in man is normally the seat of all reactions for ocular movements excited by retinal stimuli. Therefore it is necessary to study clinical material in attempting to understand the physiology of such movements in man. Since most of the otologist's observations are made on conscious subjects with cortical and visual function, he must be able to assess the role of the cortical and visual mechanisms controlling ocular movements when evaluating the role of the vestibular mechanisms in these movements. A description of some of the mechanisms illustrated by records of ocular movements2 should help to orient vestibular mechanisms for these movements among the other mechanisms.
