Cerebrocerebellum

The cerebrocerebellum receives inputs from parietal, frontal, motor, and occipital cerebral cortex relaying sensory and visual information by way of the corticopontine-cerebellar tract. Though, it also obtains input from prefrontal cortex concerned with cognitive not motor functions. The cerebrocerebellar outflow through the dentate nucleus goes to the ventrolateral thalamus that in turn projects to frontal cortex motor and prefrontal regions. Additionally, the dentate nucleus has reciprocal connections with the red nucleus. Lesions of the dentate nucleus or cerebrocerebellar cortex cause small delays and modest overshooting of movements including single joints (i.e., dysmetria). Though, for multi-jointed movement deficits are much more severe, therefore animals and patients have difficulty by using their fingers. Cognitive, involving language, deficits are also seen in patients with cerebrocerebellar damage.
