Folium (brain)
Encyclopedia
A folium is a wrinkle (gyrus
) on the surface of the cerebellum
. The cortex (skin or rind) of a folium consists of three layers of cells - the top molecular layer, the Purkinje layer, and the bottom granular layer - and this cortex covers deeper white matter
(interconnecting fibers).
Gyrus
A gyrus is a ridge on the cerebral cortex. It is generally surrounded by one or more sulci .-Notable gyri:* Superior frontal gyrus, lat. gyrus frontalis superior* Middle frontal gyrus, lat. gyrus frontalis medius...

White matter
White matter is one of the two components of the central nervous system and consists mostly of myelinated axons. White matter tissue of the freshly cut brain appears pinkish white to the naked eye because myelin is composed largely of lipid tissue veined with capillaries. Its white color is due to...
