In the central nervous system, the cell bodies and unmyelinated processes of neurons are located in the gray matter. This slide shows the gray matter of the cerebellum of the dog stained in a special way to make the myelinated fiber tracts in the center of the folded cortex and the cell bodies of the neurons black. Identify the four layers of the cerebellum. The molecular layer, which contains two types of small neurons (satellite and basket cells), the dendrites of Purkinje neurons from the Purkinje layer and the dendrites of Golgi type II cells from the granular layer and axons of granule cells. The Purkinje cell layer contains very large neurons with enormous dendritic aberrations which project into the molecular layer. The axons of Purkinje cells project deep into the brain stem. The granular layer is the dense layer of small neurons which contains granule cells, Golgi type II cells and bundles of axons and dendrites called glomeruli. The dense layer in the middle contains the axons of Purkinje cells.
