GluA2-lacking AMPA receptors in CeA are involved in acquired behavior of opioid reward. A, Behaviors of CPP in rats conditioned in 4 sessions with PBS as vehicle, morphine (10 mg/kg) without or with bilateral pre-CeA infusion (15 min before) of NASPM (40 μg, each side), or vehicle with CeA pre-infusion of NASPM. **p < 0.01 (compared to the pretest); ##p < 0.01 (compared between the indicated two groups) (n = 8 rats in each group). B, CPP behaviors in similar groups of rats with morphine substituted by AMPA (100 ng, each side) infused similarly into CeA in the conditioning procedure. **p < 0.01 (compared to the pretest); ##p < 0.01 (compared between the indicated two groups); n = 8 rats in each group.
