Granular cells of cerebellum

WebGolgi cells are large neurons scattered in the superficial part of the granular layer just below the Purkinje cell bodies. Although Golgi cell dendrites are relatively simple, compared to Purkinje cells, their dendrites extend farther in the cerebellar cortex reaching both the molecular and granular layers. Cerebellar granule cells receive excitatory input from 3 or 4 mossy fibers originating from pontine nuclei. Mossy fibers make an excitatory connection onto granule cells which cause the granule cell to fire an action potential. The axon of a cerebellar granule cell splits to form a parallel fiber which innervates Purkinje cells. The vast majority of granule cell axonal synapses a…
