In the original version of Figure 3, a dopamine D2 receptor had been positioned incorrectly and has now been moved to the correct presynaptic position on the dopaminergic neurons projecting to the basal ganglia motor circuit. In addition, the two Figure 2 citations that appeared on page 14 were incorrect and have now been changed to Figure 3.
