The cerebellar tracts travel through the cerebellar peduncles. The cerebellar nuclei send efferent impulses to the thalamus, red nucleus, and reticular formation to execute cerebellar functions. The cerebellar cortex transmits the information received from the three afferents (i.e., the cerebrum, spinal cord, and vestibular nuclei) to the four cerebellar nuclei (dentate, emboliform, globose, and fastigial) within the inner white matter. These are the cerebrocerebellum (the lateral zones), which receives sensory information from the cerebral cortex and is responsible for the planning of movements that are just about to occur (motor planning) the spinocerebellum (the vermis and intermediate zones), which receives proprioceptive information from the dorsal columns of the spinal cord and is responsible for the coordination of movements (motor execution) and the vestibulocerebellum (the flocculonodular lobe), which receives information from the vestibular nuclei and visual cortex and is responsible for balance and ocular movements. Functionally, it is divided into three zones. It consists of three lobes (the anterior, posterior, and flocculonodular lobe). The cerebellum is the part of the hindbrain that lies within the posterior cranial fossa, inferior to the occipital lobes and dorsal to the brainstem.
