Delta phase-locking is limited to a single oscillatory cycle after peakRate events. A, delta IEPC across selected peakRate events that were at least 200 ms away from preceding, and 1000 ms away from subsequent events. B, delta IEPC time course. Bottom, IEPC average across the delta range. Red horizontal line indicates baseline. Red dots indicate time points of significant deviance from baseline. C, Correlation between IEPC time courses predicted by the models and observed in the neural data. *p < 0.05.
