Centrality disruption in aMCI assessed with the centrality score. The color code is the same as in Fig. 2. For each of the five classical frequency bands, an additional graph is displayed, showing the isolated contribution of each par of frequency bands to the significant cluster of that band. The x-axis shows the interaction band, while the y-axis shows the F-value of an ANOVA that discriminates both groups (controls and aMCIs) with age and years of education as covariables
