Major Cerebellar Inputs (axons entering the cerebellum):1. Climbing Fiber Inputs = Olivocerebellar fibers-- ariseexclusively from the olivary nucleus of the caudalmedulla; have a powerful excitatory effect on Purkinjecells upon which they synapse.OlivaryNucleusPyramidOlivo-CerebellarFibers
2. Mossy fiber Inputs:A. Vestibulocerebellar fibers--arise mainly from thevestibular nerve and vestibular nuclei; project to flocculonodularlobe and fastigial nucleus (coordinate head and eyemovement.B.
