Average Regional Connection Matrix, Network Layout, and Connectivity Backbone

(A) Matrix of inter-regional fiber densities between pairs of anatomical subregions, obtained by averaging over fiber densities for all pairs of ROIs within the regions, and averaging across all five participants. Connection weights are symmetric and are plotted on a logarithmic scale. For corresponding plots for all individual participants, see Figure S2.

(B) Network layout.

(C) Dorsal and medial views of the connectivity backbone in anatomical coordinates.
