Post hoc comparisons of analysis of variance. The connection between two bars represents significant between-time differences of sReHo in five frequency bands and dReHo (^*represents significant level P < 0.05, ^**denotes significant level P < 0.01, and ^*** indicates significant level P < 0.001, Bonferroni correction). A classical frequency band, B slow 5 frequency band, C slow 4 frequency band, D slow 3 frequency band, E slow 2 frequency band, F dReHo. sReHo, static regional homogeneity; dReHo, Dynamic regional homogeneity; baseline, the rs-fMRI was performed before stimulating the trigger zone; triggering-5 s, the rs-fMRI was performed within 5 s after stimulating the trigger zone; triggering-30 min, the rs-fMRI was performed in the 30th minute after stimulating the trigger zone; ORBinf.R, right inferior frontal gyrus, orbital part; Calcarine.L, left calcarine; MOG.R, right iddle occipital gyrus; MFG.L, left middle frontal gyrus; IFGtriang.R, right inferior frontal gyrus, triangular part; AnG.L, left angular gyrus; Precuneus.L, left precuneus; MFG.R, right middle frontal gyrus; PCG.L, left postcentral gyrus; SPG.L, left superior parietal gyrus; SOG.L, left superior occipital gyrus; Putamen.R, right putamen; ACC.R, right anterior cingulate cortex; Thalamus.L, left thalamus
