Association matrix (left) and connectivity graph (right) of the networks during control and epileptiform discharges.

<p>A: Association matrix and connectivity graph at window #1 of control state. B (a), (b), (c): Association matrices and connectivity graphs at windows #1, #35 and #76, which represent three stages of the epileptiform discharges. Coordinates of association matrix correspond to channel numbers (arranged in columns) shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0092961#pone-0092961-g001" target="_blank">Fig. 1B</a>. In the connectivity graphs, the direction and strength of interactions between any two nodes (white dots) are portrayed using arrows and their line widths. Only edges with the largest 100 weights in the corresponding association matrix are shown.
