The spatial distribution of hub regions.

<p>Three dimensional rendering maps show hub regions defined by nodal betweenness (A), nodal weighted degree (B), and nodal efficiency (C) in five IMFs. The hub nodes shown in red, green, cyan and magenta color donate Associations, Primary, Paralimibic and Subcortical regions respectively as described by Achard et al. (2006) The size of the node represents their nodal topological characteristics. Hub regions are visualized using the BrainNet viewer (NKLCNL, Beijing Normal University). For the abbreviations of the regions, refer to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0124681#pone.0124681.t001" target="_blank">Table 1</a>.</p>
