Generation of connectivity networks in each group.

<p>After computing the inter-regional correlations (left), three thresholds were applied (p < 0.05, 0.025 and 0.01) and the most robust correlation coefficients (center) composed the networks (right). Networks were generated for SHAM (top), SHAM-nH (middle) and dHPC (bottom) matrices. In the matrices, colors reflect correlation strength (scale, right). In the network, the colors of the nodes are coded according to the <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1006207#pcbi.1006207.g002" target="_blank">Fig 2</a>, and the sizes of the nodes represent their degree (number of connections).
