Purkinje cells

Pur·kin·je cell lay·er

(pŭr-kin'jē),
the layer of large neuron cell bodies located at the interface of molecular and granular layers in the cerebellar cortex; dendrites of these cells fan outward into the molecular layer in a plane transverse to the folium and axons enter the white matter.

Purkinje cells

Nerve cells with very large, pear-shaped bodies and a profuse collection of dendrites that are found in the middle layer of the surface zone (cortex) of the CEREBELLUM. (Johannes Evangelista von Purkinje, 1787–1869, Czech polymath and physiologist).
