Structural properties of the human connectome. (A) The normalized coupling weights (0 ≤ W ≤ 1) and (B) Euclidean distances (in mm) in the human connectome with 66 nodes (Hagmann et al., 2008). The squares show the modules and the nodes ordered for the structural module (community) they comprise. The color bar of the weight matrix has a log₁₀ scale. The background dark blue regions in A (< 10⁻⁵) and B (= 0) indicate the absence of edges between the areas. (C) Semi-log presentation of the distribution of the weights of structural connections that span five orders of magnitude. (D) Scatter plot shows the distribution of the normalized weights of the structural connections vs. the distance between the nodes. Here we have used a linear scale for both exes.
