How the Cerebellum Differs from Other Parts of the Brain

The cerebellum is an amazing little part of the brain. Many people, however, don’t understand enough about it to really appreciate what the cerebellum does. It differs from other parts of the brain by being a simple and easy to track section that doesn’t leave much to the imagination. It controls the fine motor skills of the human body as well has some bearing on emotional response as evidenced by those who are unable to fully express their emotions caused my damage to the cerebellum. However, despite all of these little differences, there is one thing that sets the cerebellum a world apart from the rest of the human brain.

In most other areas of the brain when signals pass through they can be rerouted and reinterpreted in any number of ways given the particular section through which they pass. This recurrent internal transmission the various, separate parts of the brain develop consistent self-sustaining patterns of neural activity. However, in the cerebellum this does not occur. The little amount of recurrence that can be seen in the cerebellum is not enough to create any patterns.

Generally speaking, the cerebellum is an in and out part of the brain. It takes the information gathered through the signals and processes them in chronological order and only as they pass through once. The order in which certain signals pass through cannot be changed as the cerebellum is unidirectional and offers little recurrence. However, this doesn’t mean that the cerebellum is any less important than any other part of the brain, just that what it is designed for is quick interpretation and/or action following the signals that are sent to and through it; hence why fine motor skills are mainly controlled by the cerebellum.
