The lighter pink tissue on the surface is the “gray” matter (termed the cerebral cortex) and will contain neuronal cell bodies.

MOLECULAR LAYER: The outermost layer is the thickest, has only a random scattering of nuclei (most of which are those of neuronal cell bodies), and is lighter staining. This is termed the molecular layer.
PURKINJE CELL LAYER: Between the outer molecular layer and inner granule cell layer is a single layer of very large neuronal cell body nuclei – these are Purkinje cells (not to be confused with Purkinje fibers in cardiac muscle).
GRANULE CELL LAYER: The innermost layer is densely populated with numerous small nuclei (again most of which are neuronal cell body nuclei), and is termed the granule cell layer. It appears as a speckled purple layer.
