a The experimental paradigm and the experimental group. b The time spent immobile in the FST (n = 8/group). c Rearing numbers in the OFT (n = 8/group). d Total distance traveled in the OFT (n = 8/group). e Open-arm time proportion in the EPM test (n = 8/group). All data are expressed as the mean ± SD. **p < 0.01, ***p < 0.001, compared with control group; #p < 0.05, ###p < 0.001, compared with vehicle group.
