Functional organization of the dogfish vestibulocerebellum.
Electrophysiological and light microscopical studies were made on the dogfish vestibulocerebellum. The cell types, estimates of their numbers, and the organization of this part of the cerebellum are described and compared with the other lobes of the elasmobranch cerebellum. Electrophysiological study of the inputs to this region from the VIIIth nerves indicates that primary afferent fibres from the VIIIth nerve project to the ipsilateral granule cell layer.
