a Topographic distribution of relative beta-power changes (18–30 Hz) for the three valence classes. b Results of the topographic rmANOVA for beta power variations across valence classes. Black dots mark electrodes showing a significant effect with p < 0.05, cluster-mass correction. c Post-hoc comparisons between valence classes. Each dot represents average values computed within the cluster of electrodes shown in b for each subject. The purple dashed line marks two outliers in the neutral condition. After removal of these outliers the contrast between negative and neutral stimuli becomes significant (purple *). *p < 0.05, **p < 0.01, ***p < 0.001. d Mean spectral power changes after KCs computed as log(power_post)-log(power_pre) for each valence class (mean across electrodes depicted in b). e Source modeling analysis showing significant beta-power change differences between positive and neutral stimuli (q < 0.05, FDR correction). Medial structures depicted in black were not modeled and tested. Box-plots whiskers represent ± 1.5 IQR from Q1/Q3.
