Ask a question


The cerebellum is part of the encephalon and is composed of two hemispheres surrounding a central portion called the vermis. It is a nerve center that plays a role in the regulation of motor functions, among others. In particular, it enables the coordination of movement and balance. So when the cerebellum is affected, a set of symptoms occur: this is called cerebellar syndrome. The standing position becomes difficult with swaying and a tendency to fall, the movements are slow, inaccurate, and disordered. There is also a decrease in muscle tone. The cerebellum also interacts with other structures in the nervous system, which explains why other symptoms can be observed which are non-specific to the cerebellum when this organ is affected.
