Functional alpha-band (8-13 Hz) connectivity links that exceeded a threshold set at the 95th percentile of connectivity values (across all subjects) are depicted for visualization purposes, superimposed over spherical spline interpolated topographic maps that indicate the distribution of alpha-band power spectral density. Note that thresholding was applied here purely for visualization purposes; all statistical tests reported in the paper were conducted on graph theoretic measures derived from weighted connectivity networks.
