In the motor pathway of the basal ganglia, the nuclei that serve as the primary output structures are:
- Globus pallidus internus1
- Substantia nigra pars reticulata12
These nuclei receive information processed through the basal ganglia and project it to the thalamus—specifically the ventroanterior and ventromedial motor thalamic nuclei—before the signals are sent back to the cerebral cortex to influence movement.1
