_ _ _After neural processing of this input at the level of the cerebellar cortex, purkinje cells relay the output to the dentate nucleus, the largest of the "deep" nuclei, buried within the white matter of the cerebellar hemisphere, as shown here. This output is entirely inhibitory, and thus acts by modulating the tonic activity of neurons within the dentate nucleus.

_ _ _Neurons within the dentate nucleus have axons which begin the return route to the the cerebral cortex. These fibers exit from the cerebellum in the superior cerebellar peduncle, wrap around the central gray region of the brain stem tegmentum, and cross the midline at the midbrain level. The fibers pass through and around the red nucleus without synapsing and ascend to terminate in the nucleus ventralis lateralis of the thalamus. The thalamic neurons, in turn, relay the message back to the cerebral cortex by way of fibers that pass through the internal capsule.
