WebAug 12, 2014 · Purkinje cells, also called Purkinje neurons, are neurons in vertebrate animals located in the cerebellar cortex of the brain.Purkinje cell bodies are shaped like a flask and have many threadlike extensions called dendrites, which receive impulses from other neurons called granule cells.Each cell also has a single projection called an axon, … WebThe cerebellum consists of grey matter and white matter: Grey matter – located on the surface of the cerebellum. It is tightly folded, forming the cerebellar cortex. The gray matter of the cortex divides into three layers: an external - the molecular layer; a middle - the Purkinje cell layer; and an internal - the granular layer.
