Node Degree Distributions.

<p>Single-scale, scale-free and broad-scale <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0024678#pone.0024678-Amaral1" target="_blank">[39]</a> are characterized by Gaussian/exponential decay, power law decay, and truncated power law decay, respectively. The node degree distributions give good indication that the pediatric brain networks are broad-scale in nature. In the double logarithmic plots, the degree distribution decays linearly before a sharp cutoff. The gradient magnitudes of the fitted lines are 3.921, 2.784 and 2.764 for (a), (b) and (c), respectively.
