Fig. 5: Neural dynamics for passive sessions.

A The top row shows the group averaged topographies at different time windows following targets played at −5 dB SNR. The middle and bottom rows show the mean and variability of evoked potentials as a function of SNR, for different time windows and over a group of temporal electrodes highlighted on the topographies. Shaded areas are SEMs (n = 20 participants, from which 10 at −3 dB). B Correlation coefficient between the individual mean profiles (blue) or variability profiles (red) of projected activity in the passive session with the individual mean profiles or variability profiles of behavioral audibility during the active session (shifted by 1 or 2 SNR levels). The shaded areas are SEMs (n = 20 participants). Periods of significant correlation are denoted in thick lines of the corresponding color (one-sided t-tests, p < 0.05, FDR corrected). C Prediction of mind-wandering content from the neural projected activity under the assumption of bifurcation dynamics. The graph shows the group average performance in predicting, trial by trial, whether the participant responded that the sound was on their mind at the moment of the probe or not. All SNRs are included in this analysis. The shaded areas are SEMs (n = 20 participants). Thick dots denote periods were prediction performance was better than chance (two-sided t-tests, p < 0.05, FDR corrected). Source data for this figure are provided as a Source data file.
