Differential localization of inferior olivary neurons projecting to the tecto-olivo-recipient zones of lobule VII or crus II in the rat cerebellum.

In albino rats antidromically evoked potentials by stimulation of the cerebellar cortices of lobule VII or crus II were surveyed in the tectorecipient zone of subnucleus c in the medial accessory olive. Those from lobule VII were localized in the medial region, while those from crus II in the lateral region of the tectorecipient zone. The results confirm the tecto-olivo-cerebellar (lobule VII and crus II) projections via different inferior olivary neurons.
