Dispersion plot of the contribution ratio of spectral power within the low to very low frequency range (0.01–0.1 Hz) for COIs for the sessions of all subjects (dots), and the average contribution for each COI (plus sign). L/R SMC, left/right sensorimotor cortex; L/R AC, left/right auditory cortex; L/R IPC, left/right inferior parietal cortex.
