Cerebellum

The cerebellum monitors and regulates motor behavior, particularly automatic movements. It contains more neurons than the rest of the brain and is a site of neurogenesis.

The cerebellum monitors and regulates motor behavior, particularly automatic movements. Some recent studies have associated the cerebellum with cognitive functions, such as learning and attention. Although the cerebellum accounts for roughly 10% of total brain weight, it contains more neurons than the rest of the brain combined. The cerebellum is also one of the few mammalian brain structures where adult neurogenesis (the development of new neurons) has been confirmed.
