Power spectra of MEG data for all participants and distributions map of selected channels averaged across participants. A, The power spectra of the eyes-open and eyes-closed resting conditions for all participants. Ten-second moving time windows (10,000 time points) were used for the first Fourier transform (FFT) analysis. B, The channels used for the FFT analysis. Five combined channels (10 planar gradiometers) showing the largest alpha power were selected for each participant and were then pooled across participants. Distribution maps indicate the total selected number of combined channels at each location. Selected channels cover the parieto-occipital area.

Relationship between the alpha frequency/amplitude and tissue properties of the OR. A, The OR identified by tractography in a representative participant (left, axial view; right, sagittal view). B–D, Correlation between the peak alpha frequency (PAF) in the eyes-open resting condition and the ICVF (B), ODI (C), or MTV (D) of OR for all participants (N = 24). The negative correlation between the PAF and the ICVF was significant. E–G, Correlation between the neural activity index (NAI) at the PAF in the eyes-open resting condition and the ICVF (E), ODI (F), or MTV (G) of OR. The NAI and the ICVF/ODI/MTV were not significantly correlated.

Relationship between the beta frequency/amplitude and tissue properties of the OR. A–C, Correlation between the peak beta frequency in the eyes-open resting condition and the ICVF (A), ODI (B), or MTV (C) of the OR for all participants (N = 24). D–F, Correlation between the NAI at the peak beta frequency in the eyes-open resting condition and the ICVF (D), ODI (E), or MTV (F) of OR. None of the correlations were significant.

Relationship between the peak alpha frequency/amplitude and tissue properties of the pArc. A, pArc identified using tractography in a representative participant (left, coronal view; right, sagittal view). B–D, Correlation between PAF in the eyes-open resting condition and the ICVF (B), ODI (C), or MTV (D) of pArc for all participants (N = 24). E–G, Correlation between the NAI at the PAF in the eyes-open resting condition and the ICVF (E), ODI (F), or MTV (G) of pArc. None of the correlations were significant.
