Group average maps and time courses of event-related theta source power during 250–650 ms. In (A) 250–350 ms and (B) 450–650 ms time windows, greater theta was observed to the cognitively demanding AN words in the ASD than TD group in the LTC and left avPFC/iPFC, respectively. The vertical light-shaded bars denote the time window applied to the ROI statistical analysis. ^*P < 0.05.
