Dynamics of distance from baseline (face images, see also Figure S3A; for other categories, see Figure S3B; baseline subtracted for presentation purposes). Offsets marked by vertical lines with corresponding hues. Horizontal bars: time points of significant differences between durations (max-statistic permutations, p < 0.05; 1,500 vs. 900 ms, 900 vs. 300 ms; colors correspond to the shorter duration in the contrast). Traces are cropped 600 ms after stimulus offset (shortest inter-stimulus interval, ISI). Absolute distances are comparable within regions at different time points, not between regions, as magnitude is dependent on the number of electrodes. See also Figures S3C and S3D.
