[Sensory components of optokinetic nystagmus in exposure to the action of angular accelerations]

The relationship between the vestibular and optokinetic nystagmus was investigated using a special vestibulooptokinetic trainer. A correlation between the objective index of the angular velocity of the slow component of the optokinetic nystagmus and concomitant sensory reactions responsible for the visual perception of optokinetic stimuli was examined. It was shown that tolerance of the optokinetic system can be characterized by the differential criterion +/-deltaw that is the difference between the angular velocity of the slow component of the optokinetic nystagmus and the angular velocity of optokinetic stimuli. A group of people whose optokinetic system is highly resistant to vestibular noise had been identified. It is suggested that these findings can be used for special selection.
