[Effect of angular accelerations on the sensory and motor components of fixation eye movements]

The effect of angular accelerations on the eye fixation function and concomitant sensory reactions was investigated under special conditions. An illusion of target distortion towards the rapid component of the vestibular nystagmus developed in these situations. Changes in the eye fixation movements and "sensation of target" were coordinated and depended on the direction of the vestibular nystagmus. The findings indicate that during an exposure to angular accelerations the stability of target perceptions is disturbed and objectively recorded errors of its fixation by the optic apparatus are made.
