has soma location directly develops from granule cell cerebellar granule cell granule cell of the cerebellum An excitatory granule cell with a soma located in the granular layer of cerebellar cortex. A mature cerebellar granule cell has short dendrites with a characteristic claw-like appearance and a long axon that ascends to the molecular layer where it bifurcates (except in non-teleost fish, where it does not bifurcate) and extends mediolaterally to form parallel fibers. It has been noted in at least some mammalian species that granule cells are the most numerous cell type in the cerebellum and in the brain, with at least 99% of all cerebellar neurons being granule cells.
