Figure 1 illustrates the grand-averaged power spectra (Cz electrode) of each binge and sex group as a function of brainwave frequency. The abscissa points define the EEG bands assayed. Note the high-binge subjects demonstrate greater spectral power in the lower delta (0–4 Hz) and upper beta (20–35 Hz) frequency bands. The increase in power in the alpha (8–12 Hz) band is typical for both female and male subjects but did not differ between the sexes or among groups.
