Individual alpha frequency (IAF) peak extraction. Power spectral density plot of the resting-state EEG averaged over participants (electrodes Oz and POz as highlighted in the topographical map), showing the usual peak in the alpha band (8–12 Hz) visible with higher power in posterior electrodes (shaded are represents the SEM). The EEG power spectrum of each participant was used to estimate the individual alpha frequency (IAF) peak.
