Unilateral B-M injections in vBNST and contralateral VTA (B-M, n=11) significantly attenuated cocaine preference compared to aCSF in vBNST and VTA (aCSF, n=8) or to injections of B-M outside of vBNST and/or VTA (Missed injections, n=10) (*p<0.001 indicates a significant difference using Newman-Keuls post-hoc test). Note that disconnection of vBNST-VTA also caused a significant avoidance of cocaine paired side. Injections of B-M outside of vBNST, VTA, or both had no effect on CPP compared to aCSF microinjections into vBNST and VTA.
