<p>Whole-head topographies for grand average waveforms for the <i>Ignore</i> condition at Fc<sub>3</sub> (Ch 17) and Fc<sub>4</sub> (Ch 54) for 300ms (top), 70ms (middle) and 10ms (bottom) ISI’s are shown. Negativity up, positivity down. The standard wave is shown in blue, deviant in red, and difference (deviant-standard) in green. Vertical bars on the baseline indicate the onset of the tones. Tone 1 and tone 2 are paired stimuli.</p
