Which layer contains granule cells?

Which layer contains granule cells?

• A. Granular layer
• B. Molecular layer
• C. Purkinje layer
• D. White matter

Answer: (A)

Granule cells are located in the granular layer, the deepest layer of the cerebellar cortex. This layer is packed with tiny granule neurons that receive input from mossy fibers. Their axons then ascend into the molecular layer as parallel fibers to synapse with Purkinje cell dendrites, enabling cerebellar processing. The molecular layer contains Purkinje dendrites and interneurons, not granule cells; the Purkinje layer houses Purkinje cell bodies; white matter is made up of myelinated axons. So the granular layer is where granule cells reside.
