Post hoc comparisons of analysis of variance. The connection between two bars represents significant between-time differences of dALFF (*represents significant level P < 0.05, **denotes significant level P < 0.01, and ***indicates significant level P < 0.001, Bonferroni correction). ALFF, Amplitude of low-frequency fluctuation; dALFF, dynamic amplitude of low-frequency fluctuation; baseline, the rs-fMRI was performed before stimulating the trigger zone; triggering-5s, the rs-fMRI was performed within 5s after stimulating the trigger zone; triggering-30min, the rs-fMRI was performed in the 30th minute after stimulating the trigger zone
