Definition and function of the basal ganglia The basal ganglia are a large and functionally diverse set of nuclei that lie deep within the cerebral hemispheres. They allow the cerebral cortex to communicate with upper motor neurons in the primary motor cortex, the premotor cortex, and the brainstem. The basal ganglia allow for the smooth switching between commands that initiate and stop movement.
