Granule cell of the cerebellum
The cell bodies are packed into a thick granular layer at the bottom of the cerebellar cortex. A granule cell emits only four to five dendrites, each of which ends in an enlargement called a dendritic claw. These enlargements are sites of excitatory input from mossy fibers and inhibitory input from Golgi cells. The thin, … See more Cerebellar granule cells form the thick granular layer of the cerebellar cortex and are among the smallest neurons in the brain. (The term granule cell is used for several unrelated types of small neurons in various parts of … See more Granule cells receive all of their input from mossy fibers, but outnumber them 200 to 1 (in humans). Thus, the information in the granule cell population activity state is the same as the … See more

These cells are immortalized with the 12S E1A adenovirus gene. The granule cells of the cerebellum are one of the smallest and most abundant neurons in the brain. They account for about 3/4 of the neurons in the brain.
