Cross-correlation histograms show coincident firing of a sample pair of neurons from one SE rat between the baseline period and early preictal period.

Abstract

<p>Black line indicates the raw correlation smoothed with a 7 ms boxcar window (CCH_raw). The jitter-predicted correlation (Jitter₅₀, blue) indicates the correlation driven by common input, as determined by jitter shuffling of the spike train with a 50 ms window. The cross-correlogram (‘CCG’, or COIN₅₀, red) corresponds to pair-specific coincident activity, defined as the difference between raw coincidences and jitter coincidences.</p
