In basal ganglia: Neurochemicals
…of basal ganglia nuclei have projection neurons (neurons with axons that extend into adjacent brain areas) that utilize the inhibitory neurotransmitter gamma-aminobutyric acid (GABA). As a result, inhibitory signals form the basis of most communication between nuclei in the basal ganglia. Exceptions include the excitatory glutamate-releasing projections of the subthalamic…
