Network hub regions.

<p>High-degree nodes (shown in color on the AAL brain image; see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0196773#pone.0196773.g002" target="_blank">Fig 2</a>) are defined as exceeding mean (filled line) + 1 SD (dashed line). Degree is calculated across all frequencies. Network nodes are labeled according to the AAL parcellation scheme (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0196773#pone.0196773.g002" target="_blank">Fig 2</a>), and according to hemisphere (e.g. SMA R = supplementary motor area, right; SMA L = supplementary motor area, left). The regions are listed in order of descending degree. The 20 regions with the largest degree values are shown.
