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 the brain.) Cerebellar granule cells are also the most numerous neurons in the brain: in humans, estimates of their total ...
Cerebellar granule cells account for the majority of neurons in the human brain. [1] These granule cells receive excitatory input from mossy fibers originating from pontine nuclei. Cerebellar granule cells project up through the Purkinje layer into the molecular layer where they branch out into parallel fibers that spread through Purkinje cell ...
A set of large folds is, by convention, used to divide the overall structure into 10 smaller "lobules". Because of its large number of tiny granule cells, the cerebellum contains more neurons than the total from the rest of the brain, but takes up only 10% of the total brain volume. [11] The number of neurons in the cerebellum is related to the ...

The cerebellar network contains a large number of connections between Golgi cells. [5] The main synapse made by these cells is a synapse onto the mossy fibre–granule cell excitatory synapse in a glomerulus. The glomerulus is made up of the mossy fibre terminal, granule cell dendrites, and the Golgi terminal, and is enclosed by a glial coat. [3]
The cerebellum, or "little brain," is a portion of the brain attached to the brainstem at the pons. Among other functions, it is important for balance, coordinating movement, and maintaining muscle tone. [5] The outer layer of the cerebellum, the cortex, is made up of three layers containing two classes of neurons.
The NeuN/Fox-3 antibody binds to the small cerebellum granule cell neurons, which form a prominent layer. In contrast antibody to the close relative of NeuN/Fox-3, Fox-2, is shown in red. Fox-2 antibody stains Purkinje neurons and Golgi cell which are not recognized by the NeuN/Fox-3 antibody. The Purkinje cells form a layer above the much more ...
Purkinje neurons in the cerebellum / Cerebellar granule cells: N-type calcium channel ("Neural"/"Non-L") HVA (high voltage activated) Ca v 2.2 : α 2 δ/β 1, β 3, β 4, possibly γ: Throughout the brain and peripheral nervous system. R-type calcium channel ("Residual") intermediate voltage activated: Ca v 2.3 : α 2 δ, β, possibly γ
