Internal globus pallidus

The internal globus pallidus, and the external globus pallidus (GPe) make up the globus pallidus. In rodents its homologue is known as the entopeduncular nucleus. The GPi is one of the output nuclei of the basal ganglia. The GABAergic neurons of the GPi send their axons to the ventral anterior nucleus (VA) and the ventral lateral nucleus (VL) in the dorsal thalamus, to the centromedian complex, and to the pedunculopontine complex.
