The cerebellum, sometimes known as the "small brain," is a structure that lies underneath the occipital and temporal lobes of the cerebral cortex in the back of the brain.
Although the cerebellum makes up only around 10% of the brain's overall volume, it is home to more than 50% of the brain's neurons.
What is the function of cerebellum?
The following processes are carried out by the cerebellum:
Maintaining posture and balance-
Making postural changes to keep one's equilibrium depends on the cerebellum.
It modifies orders to motor neurons to account for changes in body position or variations in the stress on muscles using information from vestibular receptors and proprioceptors.
Balance issues are common in patients with cerebellar impairment.
2. coordination of free-will actions -
The majority of actions are made up of several different muscle groups working together and with precision timing.
Coordinating the time and force of these many muscle groups to produce fluid limb or body motions is one of the cerebellum's main roles.
3. Neuromotor abilities
Motor learning depends on the cerebellum. Through a process of trial-and-error, the cerebellum is crucial in adapting and fine-tuning motor programming to produce precise motions (e.g., learning to hit a baseball).
4. cognitive processes
Although the cerebellum is well known for its role in motor control, it also plays a role in some cognitive processes, including language.
