Supra-additive increase in power observed broadband across the entire duration of the AVFear stimulus (i.e., from 0 to 800 ms, stimulus onset through stimulus offset). Each column depicts the supra-additive response observed in a 500-ms time window beginning at 0 ms, with time windows of subsequent columns increasing in increments of 50 ms up to 300 ms. Crosshairs are placed at the MNI coordinate in the right STG (60, −46, 18) with activation thresholded from P < 0.05 to P < 0.005. T-values observed at the coordinate are as follows: 0–500 ms = 3.43; 50–550 ms = 3.19; 100–600 ms = 2.64; 150–650 ms = 2.79; 200–700 ms = 2.28; 250–750 ms = 0; 300–800 ms = 0.
