Cerebellum

The cerebellum is the major component of the hindbrain of all vertebrates. The main function of the cerebellum is to control the motor function. Some examples of motor functions of the cerebellum are coordination, movement, mental function, motor learning, balance, and posture. The cerebellum occurs in the back portion of the skull, below the temporal and occipital lobes. Moreover, the cerebellum occurs as a separate structure of the brain. In addition, the two components of the cerebellum are the cerebellar cortex and cerebellar nuclei.

The cerebellar cortex is a layer of folded tissue that contains most of the cerebellum’s neurons. In comparison, cerebellar nuclei are the innermost part of the cerebellum. In fact, the cerebellum makes up 10% of the brain and it contains 50-80% of the brain’s neurons. It also coordinates and controls voluntary movements by receiving information.  Meanwhile, the other brain areas that send information to the basal ganglia include the brainstem, cerebrum, and spinal cord.
