Fig. 6. Thalamo-subnetwork connectivity with significant variability changes in major depressive disorder (MDD) patients. Dynamic functional connectivity (dFC) variability was altered in the thalamo-Default (in state 5) (a), thalamo-DorsAttn (in state 5) (b), and thalamo-SalVentAttn (in state 1) (c) circuits. The red lines indicate a significant increase in dFC variability in MDD patients compared to the HCs. LH: left hemisphere; RH: right hemisphere; Anterior: anterior thalamus; ILM: intralaminar/medial thalamus; Lateral: lateral thalamus; Pulvinar: pulvinar thalamus; Ventral: ventral thalamus; Default: default mode network; DorsAttn: dorsal attention network; SalVentAttn: salient ventral attention 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).
