title: Electrophysiological analysis of the tecto-olivo-cerebellar (crus II) projection in the rat.
abstract: In albino rats the superior colliculus was stimulated and evoked potentials were explored in the cerebellar hemisphere including the paramedian lobule, and crura I and II. Climbing fiber responses were identified in a strip (ca. 1 mm wide) in the medial region of crus II, extending to both folia a and b. In the tectorecipient zone in subnucleus c of the medial accessory olive, antidromically evoked potentials from crus II were recorded lateral to those from lobule VII. Evidence is presented that inferior olivary neurons projecting to crus II are different from those projecting to lobule VII.
