Different frequencies of taVNS on behavior of CUMS rats. (A,B) show the comparison of sucrose preference and immobility time of FST, and (C,D) are a comparison of horizontal and vertical movement score, two contents of the open-field test, among different groups of the same abscissa point, respectively. *, **P < 0.05, P < 0.01 vs. control group and #P < 0.05, ##P < 0.01 vs. CUMS group.
