Webc) The purkinje cells receive signals from the parallel fibers which are training signals sent from the olivary nuclei (these are the climbing fibers that do that) d) The axons of the granule cells are the mossy fibers, which then synapse onto the purkinje cells (the mossy fibers deliver input to the granule cells. WebClimbing and mossy fibers comprise two distinct afferent paths to the cerebellum. Climbing fibers directly evoke a large multispiked action potential in Purkinje cells termed a "complex spike" (CS). By logical exclusion, the other class of Purkinje cell action potential, termed "simple spike" (SS), …
