Figure 9: Grand average event-related dynamics (−50 ms to 800 ms, channel P7) associated with responses to target flashes (black solid line), response to non-target flashes (grey solid line), and the difference between the two (black dashed line) (a). Zero time corresponds to feedback onset. Topographies for correct (top), incorrect trials (middle), and their difference (bottom) correspond to the latencies of the peaks of the N1 (b) and P300 (c), respectively.
