Lobular distribution of visual climbing fiber responses in the cerebellum.
The visual pathway was electrically stimulated at the optic disc, optic nerve and pretectal region in the albino rat. Field potentials of climbing fiber activation of Purkinje cells were explored in a large area of the cerebellum, and obtained in flocculus and posterior vermis. The responses in the posterior vermis were identified in the medial region of lobules VIa-c, VIII, IX, and the dorsal region of lobule X of Larsell. No response was obtained in lobule VII.
