Multiform or fusiform layer
• It contains fusiform cells in its deeper layer. Other cell types such as small
pyramidal cells, cells of Martinotti as well as stellate cells are located
superficially.
• The white matter of the cerebrum is made up of ascending and descending
tracts of sensory and motor fibers respectively.

Cerebellum

• The surface of the cerebellar cortex form deeply convoluted folds called
folia.

• Each folium is made up of an outer cortex of gray matter and an inner
medulla of white matter. The cerebellar cortex consists of three layers:

Outer molecular layer
• It is located most superficially and consists primarily of numerous dendrites
with few small stellate and basket-like neurons.

Intermediate Purkinje (piriform) layer
• It consists of a single layer of large, flask-shaped neurons called Purkinje
cells. These cells have huge cell bodies.
• It has a single axon extends down and an extensively branching dendrites
extend into the outer molecular layer.

Inner granular layer
• This layer is situated adjacent to white matter and consists of densely
packed small neurons with heterochromatic nuclei.

Functions of cerebellum
• Co-ordinates muscular activity.
• Maintain posture and equilibrium.
