Scalp maps for category and variation decodability. These maps were generated by measuring the decodability indices for each electrode separately and finally using their superposition on the scalp. The decodability values between the electrodes were calculated by interpolation as implemented in EEGLAB. (A) Pooled-condition category decodability maps. (B) and (C) Per-condition category and variation decodability maps at specific time points. The reported decodability values are averaged in the span from −25 m to +25 ms relative to the indicated time points. The dots show electrodes with significantly higher decodability values compared to the last 200 ms prior to stimulus onset (as evaluated with Wilcoxon’s signed rank test with correction for multiple comparisons).
