The dopamine D3 preferring ligand R-(+)-7-OH-DPAT induced strong hypolocomotion in rats. Doses producing reduction of locomotion failed to affect dopamine release or synthesis rate. These data support the hypothesis that the dopamine D3 receptor is a postsynaptic receptor with an inhibitory influence on rat locomotor activity.
