Fig. 2.

Whole-brain anatomical connectivity used in the model. The network is composed of 96 nodes, each corresponding to brain regions from the regional map (RM) parcellation of Kötter and Wanke (59) (Methods). Region labels are given on the left. (A) Matrix of connectivity weights, representing the density of axonal connections between every pair of nodes (arbitrary units [au]). Higher (brighter) values of the connection weights denote denser connections; black entries indicate no anatomical connection for that node pair. (B) Matrix of tract lengths, as approximated by Euclidean distances between the centroids of each area in the (human-modified) RM parcellation.
