Fibers reaching directly to Purkinje cell of cerebellum arise from which of the following:
Vestibular nucleus
Inferior olivary nucleus
Raphe nucleus
Locus ceruleus
Functional unit of cerebellum = Purkinje cell neuronal circuit of the Purkinje cell: - Afferent inputs of cerebellum Climbing fiber type Mossy fiber type Originate from inferior olives of the medulla. Enter cerebellum from multiple sources - cerebrum, brainstem &spinal cord. Send collaterals to excite deep nuclear cells & then proceed to synapse with granule cells. Output from - deep nuclear cell Excitatory influence from direct connection with cerebellum from the brain or periphery Inhibitory influence from Purkinje cell
