Fig. 4: Comparison of neural activity in the active and passive sessions.

A Group averaged topographies at various time windows following stimulus presentation in the active and passive sessions at −5 dB. Group averaged evoked potentials at Cz for the different SNRs in the active and the passive sessions. B Classification scores (AUC) for the cross-classification analysis, at an SNR of −5 dB. Regions where classification was significantly different from chance are outlined in black (two-sided non-parametric sign test76, p < 0.05, FDR-corrected). C Source reconstruction at 330 ms post-stimulus. The activation maps show the t-values of a paired t-test across subjects between mean activations for stimulus present at −5 dB versus stimulus absent, in the active or passive sessions (left and middle) and between mean activations for the active versus passive session for stimulus present at −5 dB (right). Only significant activations are shown (p < 0.05, FDR corrected). D Group averaged time course of source reconstruction in three regions of interest, shown for the active or passive sessions (SNR = −5 dB as above). Thick gray dots indicate periods of significant difference (two-sided paired t-tests, p < 0.05, FDR corrected). Source data for this figure are provided as a Source data file.
