Which cerebellar cortex layer contains Purkinje cells?

Which cerebellar cortex layer contains Purkinje cells?

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

Answer: (A)

Purkinje cells sit in a distinct single layer of the cerebellar cortex—the Purkinje layer. This layer lies between the molecular layer above and the granular layer below. The large Purkinje cell bodies occupy this layer, while their expansive dendritic trees reach up into the molecular layer to receive inputs, and their axons project to the deep cerebellar nuclei. The molecular layer contains the Purkinje dendrites and other processes, the granular layer houses numerous small granule cells, and the white matter contains myelinated axons rather than neuronal cell bodies. So the layer that contains Purkinje cells is the Purkinje layer.
