Figure 4.
Fos-GAD67 overlap in the BLC, NAcc, and PrL after CPP testing of drug-paired versus unpaired animals. Data are expressed as the percentage of Fos-IR cells in each region that are GAD67-IR. Greater Fos-GAD67 double-labeled neurons were found in PrL, but not BLC or NAcc, of drug-paired animals. *p < 0.001; one-way ANOVA.
