Fig. 2.
The grand-average ERPs at Fz in the different conditions for the standard (thin lines) and deviant (thick lines) pairs. A–C: The ERPs for the high-stream and low-stream stimuli in the ignore conditions. D: The ERPs from the attend condition for the attended-stream and unattended stream stimuli. The black rectangles indicate the timing of the stimulus pair (50-ms tone, 30-ms gap, 50-ms tone). The MMN is the late negative enhancement in the deviant-pair ERPs compared to the standard-pair ERPs.
