Features with an asterisk represent those with an overlap in histograms between pre- and post-AAR ≥ 80%. Last four sections show, from top to bottom, the number of features that belong to each of the four feature sets, brain regions, frequency band, and montage, respectively. Values reported between parentheses represent those with pre-post AAR histogram overlap ≥ 80%.
