Beta-band power decreases in the amygdala during the Response phase (RES) compared to the Fixation phase (FIX). A) Trial-averaged power spectral density (PSD) plot from a gray matter electrode contact in the amygdala in a representative participant, shaded regions represent the boot-strapped (n = 10,000) 95 % confidence intervals. B) Half-histogram/half-violin paired observation plot of trial-averaged power calculated over the frequency of significant modulation as determined by the nonparametric cluster-based permutation test (n = 1000, p < 0.05) for a representative gray matter electrode contact, gray lines represent individual trials in the 3 phases.
