The cerebellum is located at the base of the brain and is separated from the overlying cerebrum by a layer of dura mater. Its connections with other parts of the brain travel through the pons. The cerebellum is responsible for coordinating movements, posture and balance.
The cerebellum is composed of an outer cerebellar cortex and inner medulla of cerebellar white matter with a deep cerebellar nucleus. The adult cerebellar cortex contains three molecular layers: the inner granule layer, which contains the granule cells and Golgi cells, the Purkinje cell layer, which contains Purkinje neurons and Bergmann glia, and the outer molecular layer, containing the basket and stellate interneurons.
