Number of SOZ channels, spectral peaks with significant spectral changes during fast epileptic activity (FEA) compared to baseline (q level < 0.001, Wilcoxon Ranksum Test, FDR correction) and mean values ± standard deviations of peak frequency, bandwidth, Q factor and maximum power, for individual patients, C: contacts. Please note the wide range of bandwidth and power within and between patients.
