Top: 85 × 85 mean connectivity matrices (unthresholded) of inter-region connection weights averaged across all participants (N = 3,153) for six network weightings and generated from the same set of streamlines. In each case, the two large rectangular patterns on the diagonal correspond to the left and right hemispheres. Bottom: the corresponding histograms of nonzero edge weights pooled across all participants for each weighting (SC is log-scaled). SC = streamline count, FA = fraction anisotropy, MD = mean diffusivity, ICVF = Intracellular volume fraction, ISOVF = Isotropic volume fraction, OD = orientation dispersion.
