Abstract
The cerebellar flocculus of the cat be divided into three zones (rostral, middle and caudal) anatomicaly and physiologically. The rostral zone receives climbing fiber input from the rostral part of the dorsal cap and the ventrolateral outgrowth, and sends output to the central part of the superior vestibular nucleus. The middle zone receives climbing fiber input from the caudal part of the dorsal cap and sends output to the medial vestibular nucleus. The caudal zone receives climbing fiber input from the ventrolateral outgrowth and the rostral part of the dorsal cap, and projects to the Y-group and the medial part of the subnucleus lateralis parvocellularis of the lateral cerebellar nucleus, Activation of the rostral, middle and caudal zones produces an upward, an ipsilateral horizontal and a downward eye movement, respectively.
