WebHorizontal smooth pursuit of a 0 5 deg visual target is limited to velocities of less than 1 deg/sec. However, moving an optokinetic background with the 0 5 deg target enables the cat to achieve higher horizontal smooth eye velocities of up to 8-5 deg/sec. Prolonged (10-20 sec) constant velocity rotation of an optokinetic drum evokes horizontal ...

Optokinetic testing and suppression of the vestibulo-ocular reflex by visual fixation are two other ocular motor functions related …
WebThe optokinetic response ( OKR) is a combination of a slow-phase and fast-phase eye movements. It is seen when an individual tracks (pursuit movement) a moving object with their eyes, which then moves out of the field of vision, a point at which their eyes move back to the initial position (saccade movement) when they first saw the object.
