a Distribution of t-values where fearful-neutral differentiation varied between rTLR patients and the unweighted average across all groups (summed cluster tGroup (rTLR) × Emotion = −1421.000, p = 0.0002; n = 18 per group). The topography is averaged across time-points (95–300 ms) and frequencies (60–80 Hz) of significant effects. Time-frequency plots are averaged across channels. Significant channels and time-windows are outlined or marked in black. b Distribution of differential GBA power within the cluster of the significant Group (rTLR) × Emotion interaction. c Distribution of power values per group and condition extracted from the channel clusters, averaged across time-points and frequencies within the respective cluster. Topographies depict grand-average GBA scalp distribution, averaged across time-points and frequencies of the corresponding effect. For all boxplots, whiskers indicate the interquartile range. The bold horizontal line indicates the distribution median. Dots indicate single-subject values. Black squares indicate the distribution mean. lTLR patients with apical resections (spared hippocampus, n = 5) are marked in blue. Brackets mark significant comparisons that specify interactive effects of Group and Emotion (***p ≤ 0.001). Abbreviations: GBA gamma-band activity, HC healthy controls, lTLR left temporal lobe resection, ns not significant, rTLR right temporal lobe resection.
