Four contrasts were analyzed by eLORETA Log-F ratio statistics (with 5000 randomizations): HV vs. SCZ; LDD vs. SDD; HV vs. SDD; HV vs. LDD. In each contrast, a unique Bonferroni-corrected two-tailed p-value was produced for all ROI pairs in the six frequency bands (n = 2268). Significant threshold was set at p < 0.01. The visualization of brain networks was performed using BrainNet Viewer (http://www.nitrc.org/projects/bnv/) Matlab toolbox (Xia et al., 2013).
