The Purkinje layer is a single, distinct row of large Purkinje neurons located in the cerebellar cortex of the cerebellum. In the cerebellar cortex, there are three layers: the molecular layer, the Purkinje cell layer, and the granular layer. Purkinje cells have extensive dendrites that extend into the molecular layer to receive inputs, while their axons project to the deep cerebellar nuclei, providing the primary inhibitory output from the cerebellar cortex via GABA. This unique arrangement and function are specific to the cerebellum, so the Purkinje layer belongs to the cerebellum, not the cerebrum, hypothalamus, or midbrain.
