Fig. 6: Comparison between minimum mean cross-entropy (MMCE) and superlets.

a MMCE using 7 windows that span 30–700 ms on EEG data recorded by 15 occipital electrodes. b Adaptive multiplicative superlets on data from a, with orders spanning 1–15 and c1 = 3 cycles. For each analysis, signals were aligned to stimulus onset (left) or subject response (right). Representations were first logarithmized (base 10) and then baselined (z-score) to the pre-stimulus period. Color scales were maintained identical across conditions (along columns) to facilitate comparisons. Number of analyzed trials per condition were: 84 for “seen,” 20 for “uncertain,” 100 for “nothing.” c MMCE using 7 windows that span 50–700 ms on in vivo electrophysiology data (LFP, 10 trials). d Adaptive multiplicative superlets on the data from c, with orders spanning 1–15 and c1 = 3 cycles. e Analyses on restricted windows with various locations and sizes (see insets in c and d) using MMCE (top) and superlets (bottom). The power scale is logarithmic in c and d, to facilitate exploration of a large spectral range, while it is linear in e, to enable precise quantitative comparison.
