Information-selectivity in different brain areas. (A) Information-selectivity matrices showing, in color codes and at specific time points relative to stimulus onset, the entangling of category and variation processing in the brain. Colors show the amount of correlation (Pearson linear correlation) between decodability indices obtained from whole-brain EEG electrodes in the decoding of specific aspects of information with higher values showing more similarity (information non-selectivity). (B) Time-resolved information-selectivity, measured as the difference between the sums of within-information correlations minus the sum of across-information correlations. Red arrows indicate the time points used in (A). The black circles indicate the time points at which the information-selectivity index was significantly (i.e. p < 0.05, evaluated using Wilcoxon’s signed-rank test) different from the same index averaged in the last 200 ms window prior to the stimulus onset (before baseline removal). Shaded areas indicate the SEM across subjects.
