Dopamine D4 receptors are localized in the GABAergic projections that globus pallidus (GP) neurons send to the reticular nucleus of the thalamus (RTN), the substantia nigra reticulata (SNr) and the subthalamic nucleus (STN).

It is then, unexpected that systemic injections of D4 ligands have no significant effects on the motor activity of normal rats.
