For each of the selected automated anatomical labelling (AAL) regions of interest (ROIs; left Heschl’s gyrus [LHG], right Heschl’s gyrus [RHG], left hippocampus [LHP], right hippocampus [RHP], anterior cingulate gyrus [ACC], medial cingulate gyrus [MC], plus left and right occipital superior lobe for comparison purposes), three plots are provided. First, we illustrate the power spectrum computed using complex Morlet wavelet transform for the M and NT1 conditions. The power spectra were baseline corrected by subtracting, for each frequency, the average power in the baseline interval from the power at all time points. The colorbar indicates squared femtotesla (fT2). Second, we illustrate the significant results emerging from the contrasts between the power spectra of M versus NT1 (two-sided t-tests [n = 83 participants] and cluster-based Monte-Carlo simulations [MCS; MCS, α = 0.05, MCS p-value = 0.001] correction for multiple comparisons). In this case, the colorbar indicates the t-values obtained by contrasting M versus NT1. Source data are provided as a Source Data file.
