Changes in functional connectivity across all neuronal pairs from cross-correlation analysis.

<p>Upper panel shows the raw correlation (CCH_raw), correlation driven by common input (Jitter₅₀), and correlation of neuronal pairs (COIN₅₀) based on peak values at baseline and early preictal periods. Lower panel shows log ratios of the coincident peak of early preictal period to that of baseline period. The vertical scatter plots integrate the distributions of all ratio results in CCH_raw, Jitter₅₀, and COIN₅₀. Each data point represents a result from one neuronal pair. The mean peak ratio is indicated by black horizontal line, and the median peak ratio is shown in green. The correlation value of neuronal pairs was significantly larger in nonSE rats than SE rats.
