The results from the statistical comparison (Group-level analysis) of averaged connectivity patterns between patients and controls. Each pairwise coupling was compared independently, for every band and recording condition, by means of Wilcoxon rank sum and the significant ones (p < 0.05; corrected for multiple comparisons) are indicated as non-zeroed entries of a “connectivity matrix”, with a color code that encapsulates the difference in strength (of the median values in the corresponding groups). Red hue has to be interpreted as higher coupling in patients and green hue as higher coupling in controls, while color intensity reflects the strength of this effect. The absence of green hue in the diagrams clearly indicates the increased coupling in patients group compared to the control group
