Cerebellum Location and Primary Function

The Cerebellum is one of the most important parts of the brain.  It is located at the rear end of the brain under the cerebral hemisphere. It is differentiated from the Cerebrum from its folded lines accordion structure. It is also attached to the brains stem with the help of pons. Its distinctive parallel groves make it apt for motor signal transmission.

It is the second largest part of the brain, following the Cerebrum. Traditionally, the Cerebellum is known only as a center to control motor responses. It was believed that the Cerebellum would solely focus on the enhancement and modification of motor signals and enable the body to make smooth movements and even smoother transitions from one movement to the other. Moreover, it was known to be the primary part responsible for the muscle movement and coordination. The Cerebellum also plays a very important role in vision and auditory system. It does the balancing act for the body and maintains the posture of the body.

However, some initial studies have shown a deep correlation of the Cerebellum with Cognitive functions. These functions include the learning of a new language and the experience of some very primitive emotions like fear. In spite of the fact that the Cerebellum has very brilliantly engineered cells like Purkinje and Granule Cells, it is not the seat of the brain where responses are to be gathered and analyzed, as per the studies.

In fact, activities where the muscles or the physical movements have to be learnt are all coordinated and adapted by the Cerebellum. For example, when children learn to play baseball, they learn exactly when to hit the ball with the bat. The Cerebellum plays a primary role in this case. Not only would it decide when to hit the ball, it would also note the distance and speed which will help our reflexes. Similar instances of the adaptive functions of the Cerebellum activities include driving and playing sports.

A cerebellum dysfunction may lead to lack of motor responses, the most important and widely studies feature of this part. The person with such a dysfunction may not walk properly and may not be able to respond well to physical stimuli. He may not be able to balance his posture and coordinate his muscles properly. This is often a result of a stroke and may additionally cause dizziness and nausea.

    Interesting. The cerebelum function are more complicated that we know them …
