ERP comparison between pollution and clean air cues in attention-holding trials. (a) Topographic plots of ERP waves show the brain activities in attention-holding trials per 200 ms with pollution images (the first panel) and clean air images (the second panel) as the cue. The third panel shows the ERP difference waves between pollution and clean air conditions. (b) Mean ERP waves for the channels of N300 ROI. (c) Mean ERP waves for the channels of P300 ROI. Gray rectangles indicate time windows of interest.
