Figure 4. The effects of right CeA morphine on CPP and dopamine release are blocked by rACC β-funaltrexamine.
(A) In SNL rats, CPP to morphine infused into the right CeA is observed only in rats that were pre-treated with saline, but not β-FNA, in the rACC (n= 12; *p=0.0267; one sample t-test). (B) Microdialysis shows that NAc dopamine levels are increased following morphine administration into the right CeA in SNL rats pre-treated with saline, but not β-FNA, in the rACC (n= 11–15; *p=0.0129; unpaired t-test). Data are shown as means ± SEM.
