Extended Data Fig. 4. Source space trait alpha peak frequency correlations with perceptual threshold (cf. Supplementary Table 15).

Source space pre-stimulus trait alpha peak frequency correlations with temporal binding window estimates obtained from each experiment. In the ‘yes-no threshold’ experiment the binding window size is given as the asynchrony yielding approximately 50% performance accuracy for ‘2 flash + 0 sound’, ‘2 flash + 1 sound’, and ‘1 flash + 2 sound’ trials. The alpha temporal resolution hypothesis, based on previous studies, predicts a negative correlation between alpha frequency and temporal binding window length^30–32. Bayes factors (BF) show the evidence for HA relative to H0 plotted on a log10-scaled ordinate. Purple lines indicate thresholds for moderate evidence favouring H₀ (< 1/3) or H_a (> 3)⁷⁷ SEM, Standard error of the mean.
