Cocaine differentially regulates FGF13 mRNA levels in environmentally enriched versus environmentally isolated conditions. Bar graph comparing FGF13 mRNA levels in the NAcSh of either environmentally enriched or isolated rats that self-administered saline or cocaine. A significant main effect of cocaine (shown) and an interaction effect (cocaine × housing effect) were found. Data are mean ± SEM (n = 7–8 rats/group). Significance was assessed with a likelihood ratio F-test (**p < 0.01).
