Behavioral studies were conducted in rats administered a selective D3 agonist, 7-hydroxy-N,N-di-n-propyl-2-aminotetralin (7-OH-DPAT) or 4aR, 10bR-(+)-trans-3,4,4a,10b-tetrahydro-4-propyl-2H,5H-[1] benzopyrano[4,3-b]-1,4-oxazin-9-ol (PD 128907). Both drugs induced disruption of huddling behavior in rats at doses that did not produce hyperlocomotion. The effects of the D3 agonists were dependent upon dosage and time after administration. These results suggest that D3 receptors are concerned with social interaction in rats.
