Cerebellum Function:

Did you know that the cerebellum is the only region in rodents' brains with a foliated structure? The cerebellum, or the 'little brain,' is made up of 80% of the neurons in the human brain. The cerebellum is used for motor performance and cognitive and social functions.

Structure:

• Cerebrocerebellum

• Spinocerebellum

• Vermis

• Vestibulocerebellum

• Cerebellar Peduncles

The cerebellum structure is organized into four sections: the Cerebrocerebellum, Spinocerebellum, vermis, and vestibulocerebellum. The Cerebrocerebellum receives input from the cerebral cortex and is responsible for planning and initiating movements. The Spinocerebellum receives information about limb positions and touch sensations from the spinal cord. This information is then used to find discrepancies and correct them. The vermis is the area of the Spinocerebellum that runs along the midline and is responsible for posture and limb and eye movements. The vestibulocerebellum maintains equilibrium, such as balance and posture. Finally, the Cerebellar Peduncles are pathways that allow the cerebellum to communicate with the rest of the nervous system

Cellular Level: The cerebellum has dozens of major cell types, all organized into a layered folded cortex's.
