Group average maps and time courses of event-related theta source power in the 700–1000 ms time window. The top row shows greater theta to SW (right) and AN (left) in the ASD than TD group in the ACC. The bottom row demonstrates similar response-related theta enhancement to SW (vs. PW) and AN (vs. PW) in the right motor cortex (R MotCx) across the groups, and less suppressed theta to SW and AN in the ASD than TD group in the L MotCx. The vertical light-shaded bars denote the time window applied to the ROI statistical analysis. ^*P < 0.05.
