DMN CC index analysis results. Only the results showing significantly different global CC indices are presented. For each frequency band, key ROIs are highlighted on the brain image left side; additionally, if more than one is included, common key ROIs are also illustrated as a form of DMN pattern. DMN patterns and the comparisons of global CC indices are presented right side. In the bar charts, red bars indicate disorder groups, and blue bars show HC groups. The error-bars indicate standard error. (a) In the theta band DMN, SZ and AD commonly showed strong hyper-clustering in four regions: left superior frontal gyrus (R8), left middle occipital gyrus (R12), right precuneus (R17), and right superior temporal sulcus (R23). (b) In the alpha1 band DMN, MCI, OCD, and AD commonly showed hypo-clustering in the left lingual gyrus (R10). (c) In the beta1 band DMN, OCD showed strong hypo-clustering in the right superior temporal sulcus (R23). (d) In the beta2 band DMN, MDD showed strong hyper-clustering in the right lingual gyrus (R11). ^†p < 0.07, *p < 0.05, **p < 0.01 (SZ schizophrenia, AD Alzheimer’s disease, OCD obsessive compulsive disorder, MCI mild cognitive impairment, MDD major depressive disorder, HC healthy control).
