This region of the Brain plays an important aspect of body control.
The function of the cerebellum is as follows:
-Â Sensory perception
-Â Motor Control
-Â Muscle Control
It is located in the “hindbrain”
Contains more then half of all neurons in the brain
More then 200 million fibers act as input triggers in the cerebellum.
Age causes change changes to the cerebellum including size, amount of white matter, and others.
1.)Â Anterior lobe
2.)Â Posterior lobe
3.)Â Flocculonodular Lobe
Deep Nuclei – is the main center of communication
Layers of the Cerebellar Cortex
1.)Â Granular layer – innermost layer that contains 3 cell types
1.) Granule cells
2.) Unipolar brush cells
3.) Golgi cells
2.)Â Purkinje layer – middle layer
Purkinje cells are found here that provides its only source of “output”.
Input can also be seen here as well.
3.)Â Molecular layer
1.) StellateÂ – synapse into Purkinje Cells
2.) Basket Cells – synapse into Purkinje Cells
