WebOptokinetic reflex, changing eyes back to their previous position after focusing on an object. Saccades, quick motions that shift your gaze from one object to another. Smooth pursuit (visual tracking), which enables you to hold your gaze on a moving object. Vestibule-ocular reflex, which adjusts eye positioning when your head is moving. WebThe vestibulo-ocular reflex (VOR) plays a major role in ocular motility. Stimulation of each semicircular canal produces excitation of a specific extraocular muscle and inhibition of its antagonist in each eye. Floccular inhibition of the VOR has been extensively studied in the rabbit. Inhibitory projections from floccular Purkinje cells reach ...
WebOptokinetic stimulation activates visual climbing fiber pathways that synapse upon contralateral floccular Purkinje cells. Long-term horizontal optokinetic stimulation causes a progressive decrease in gain of the optokinetic reflex and leads to the subsequent genesis of a prolonged negative optokinetic afternystagmus. WebIn a reflex mechanism called optokinetic nystagmus, the eyes pursue a moving scene to keep the image stationary on the retina. When they can move no farther, they snap back …

WebReflex pathways In examining any reflex movement, one must look for the sensory input—i.e., the way in which messages in sensory nerves bring about discharges in the motor nerves to the muscles. This study involves the connections of the motor nerves or nuclei with other centres of the brain.
