Figure 4.

Communication loops between the striatum and the cerebellum shown on the left of this schematic representation. (A) Striatal input from the caudate nucleus (CN) and putamen (P) (shown in orange) is routed via the thalamus (Thal) to the dentate nucleus (DN) of the cerebellum. (B) Input from the subthalamic nucleus (STN) of the basal ganglia is directed through the pontine nuclei (PN) of the pons to the cerebellar cortex (shown in green). Communication pathways between the basal ganglia and the cerebral cortex are shown in blue on the right of the schematic. (C) The subthalamic nucleus has direct connections to the cerebral cortex as well as indirect connections to the cerebral cortex via thalamus and the globus pallidus (GP). (D) The thalamus has direct reciprocal connections with the cerebral cortex.
