CENTRAL NERVOUS SYSTEM
The gray matter of each folium is organized into three distinct layers, which contain the cell bodies and nuclei of neurons and glial cells.
The outermost layer, called the molecular layer, contains relatively few neuronal cell bodies.
The middle layer, called the Purkinje cell layer, consists of a single row of large Purkinje neurons.
The innermost layer, adjacent to the white matter, is the granular layer. It contains a large number of small neuron cell bodies that are ensely and compactly arranged.
A thin layer of white matter forms the central axis of each folium. It lies between the granular layer of one folium and the molecular layer of the adjacent folium. The white matter contains numerous nerve fibers and glial cells.
CEREBELLUM – 2
The rectangle in the upper figure indicates the region of a cerebellar folium shown in greater detail in the lower figure.

A transverse section of the cerebellar folia shows the gray matter of each folium highlighted in a slightly different color. The white matter forms the central core of each folium and is highlighted in pink.
The surface of the folia is not smooth. Instead, it has numerous small indentations and folds that give the surface its characteristic appearance.
The gray matter of the cerebellum consists of three distinct layers, which are described in detail on the following pages.
