Figure 1:
Effect of intra-CeA injections of URB597 on alcohol self-administration in a) msP rats and b) Wistar rats. URB597 at the doses of 0.1 and 1.0 μg/rat decreased alcohol-reinforced active lever responding in msP but not Wistar rats. Values represent the mean ± (SEM) of number of rewards obtained by active lever responding (top panel) and responses on the inactive lever (bottom panel). Significant differences from vehicle-treated rats (Veh): *p<0.05, **p<0.01.
