FIGURE 7.
MAMPH administrations were tested to label c-Fos expression in the NAc and the amygdala’s CeA, and BLA for the control (n = 6), MAMPH (n = 6), PrL(+)/MAMPH (n = 6), and PrL(–)/MAMPH groups (n = 6) by injecting NMDA or saline into the PrL. PrL(+): Injection of a low concentration of NMDA to excite the PrL neurons; PrL(–): Injection of a high concentration of NMDA to destroy the PrL neurons. Differences in c-Fos expression levels in the NAc, CeA, and BLA among all groups were analyzed by one-way ANOVA, followed by Tukey’s post hoc test if a significant difference was appeared among groups. ∗p < 0.05 indicates significant differences compared with the control group; #p < 0.05 indicates significant differences compared with the MAMPH group.
