Facts and curiosities of the cerebellum

Although the brain is the main and most important organ of the nervous system , that CPU that makes everything in our body work through commands and stimuli-responses, the brain is made up of other parts besides the brain that are still just as necessary, although perhaps less well known. Among them, today we want to highlight the cerebellum; that little brother we remember little about but who is always there .

The cerebellum is located at the back and bottom of the skull, under the occipital lobes of the brain. It is mainly characterized by the large concentration of neurons it presents (approximately half of those in the entire brain) and its function is related to movement and, therefore, to the motor system . Balance, voluntary muscle movements and coordination are the responsibility of the cerebellum and functions or responses are still being found in which the cerebellum could intervene. Its importance lies, among other things, in the many connections it has with the cerebral cortex and that allow it to coordinate the information received through biochemical reactions so that it reaches the cortex.

The information available on the cerebellum increased from the 19th century, when experiments began (especially in France) with this organ and its possible effects on the body. For example, their surgical removal was found to cause muscle movement and coordination disorders . Since then, knowledge has not only grown about its functions but also about the diseases that affect it. Hypotonia, uncontrolled tremors, loss of strength and speed, or ataxia are some of the most common problems associated with the cerebellum.

The importance of the cerebellum has grown as the functions it performs in the human body and its role as part of the brain became known. To continue raising awareness of the cerebellum and disseminating the importance of caring for it against the possible conditions that may arise, here are some curiosities about the brain’s little brother .
