Values are means ± SE. Summary of single-subject results, as well as the group magnitudes and signal-to-noise ratios (SNRs) at each frequency of interest of the auditory steady-state response (ASSR) and steady-state visual evoked potential (SSVEP). The “Number of Subjects” column indicates the number of subjects (out of 25) that showed a significant response for each component (using Bonferroni-corrected P thresholds). These results were derived from the magnitude spectra and noise floor estimates that were averaged in frequency space across epochs and draws, within the bootstrapping algorithm.
