LF: laterality fluctuation; LH: left hemisphere; RH: right hemisphere; Anterior: anterior thalamus; ILM: intralaminar/medial thalamus; Lateral: lateral thalamus; Pulvinar: pulvinar thalamus; Ventral: ventral thalamus; Vis: visual network; SomMot: somatomotor network; DorsAttn: dorsal attention network; SalVentAttn: salient ventral attention network; Limbic: limbic network; Cont: executive control network; Default: default mode network; Temp_4: the fourth region of the temporal cortex (middle temporal gyrus); PFCdPFCm_4: the fourth region of the dorsal/medial prefrontal cortex (medial superior frontal gyrus); PFCdPFCm_5: the fifth region of the dorsal/medial prefrontal cortex (superior frontal gyrus); FEF_2: the second region of the frontal eye fields (superior frontal gyrus); FrOperIns_3: the third region of the frontal operculum insula (insula); ns: non-significant. ↓indicates a significant decrease in MDD; ↑indicates a significant increase in MDD. * indicates a significant correlation with the HAMD score.
