Extended Data Fig. 5: Distribution of spectral band power across multidien IEA cycles.
From: Hippocampal network activity forecasts epileptic seizures
(a, top) Polar plot showing seizure likelihood (purple) predicted by phase of multidien IEA cycles (n = 15 subjects). Linearized depiction of fluctuating seizure likelihood as a function of phase over two cycles to aid visualization of continuity at cycle edges (bold, mean; shading, SEM). (a, bottom) Relative change in spectral power per frequency band (y-axis) over two multidien IEA cycles (x-axis) aggregated across participants (n = 15). There is a broadband increase in spectral power near the peak and falling phases of the multidien IEA cycle. No significant population-level effect was observed at the trough or rising phase of the multidien IEA cycle. Color intensity, spectral power effect across subjects; lines, 99% confidence intervals.
