Figure 7. Expression of GABAA-Rα4 in brain regions of rats in each group. Red labeled GABAA-Rα4, nuclei were labeled with DAPI (blue). (A) α4 subunit expressions in the prefrontal cortex of rats. (B) α4 subunit expression in the hypothalamus of rats. (C) α4 subunit expression in the amygdala of rats. (D) α4 subunit expressions in the hippocampus of rats. Compared with normal group: *p < 0.05, **p < 0.01; compared with the model group, #p < 0.05, ##p < 0.01.
