The lateral globus pallidus (or external GPe) receives a strong glutamatergic projection from the subthalamic nucleus. The two form a particular system: a coupled pacemaker.The axons of the external globus pallidum go essentially to the subthalamic nucleus. They go also to other elements of the basal ganglia system the striatum the substantia nigra pars reticulata and the internal globus pallidus where they release the neurotransmitter GABA.
