Electrical stimulation of the caudal zone of the cat's cerebellar flocculus evoked a downward smooth eye movement. Electrolytic injury of the vestibular group y nucleus abolished this smooth eye movement. There may be a pathway from the caudal zone to the extraocular motor nucleus via group y nucleus related to vertical smooth eye movements. This pathway may contribute to the vertical optokinetic system in driving a vertical slow phase and/or smooth pursuit eye velocity. It also apperared that the cerebellar flocculus contributes to the optokinetic system in driving a horizontal slow phase and/or smooth pursuit eye velocity.
