✦ Synopsis


Neurons which receive an input from the horizontal semicircular canals were recorded from the vestibular nuclei in chronically prepared monkeys (Macaca mulatta) during optokinetic after-nystagmus (OKAN). In complete darkness the vestibular neurons showed activity changes which closely paralleled the strength of nystagmus. The activity of vestibular units returned to baseline levels of spontaneous discharge only when all after-nystagmus had ceased, or when it was inhibited by stationary visual stimuli. The possible role of vestibular neurons in the generation of OKAN and its significance in vestibulo-visual interaction is discussed.

In six rhesus monkeys (Macaca mulatta) the effect of repetitive periods of whole-field optokinetic stimulation upon the different phases of optokinetic after-nystagmus (OKAN) was studied. The preceding optokinetic stimulus consisted of rotating a striped cylinder around the stationary monkey. Experi
