Fig. 6: HFO synchrony is the strongest during moments of high-amplitude HFO.

a Histogram of the HFO amplitude coincidences for all pairs of contacts (C1 and C2), showing a saddle with peaks when both amplitudes are either at their highest or lowest values. b Absolute mean deviation (%) of numbers of samples in a from uniform distribution as a function of high-gamma frequency. Shaded areas indicate bootstrap confidence intervals for the mean (5 and 95%-tile, Nbootstraps = 1000)). c Moment-to-moment HFO synchronization (PLV) for SEEG electrode contact pairs (C1, C2) is dependent on the HFO amplitude at both contacts. Each matrix element is the mean of instantaneous PLV between all significant contact pairs as a function of their moment-to-moment normalized amplitudes. d Mean absolute deviation (%) of the observed PLV in bins of contact amplitudes (see c) from uniform distribution as a function of high-gamma frequency. Shaded areas indicate bootstrap confidence intervals for the mean (5 and 95%-tile, Nbootstraps = 1000).
