Fig. 1 — Effects of treatment on resting-state EEG in the central ROI. Analysis of absolute and relative power in controls and in patients for the four therapy conditions. Absolute and relative power spectra were subdivided into five frequency bands (delta, 2–4 Hz; theta, 4–8 Hz; alpha, 8–13 Hz; beta, 13–30 Hz; gamma, 30–48 Hz). (A) Comparison of absolute power spectra. Inset, location of the seven averaged electrodes of the central ROI used for analysis of power. (B) Topographies of absolute power for controls and patient groups. (C) Absolute power in the five frequency bands. Inset, enlarged version of the distribution for absolute beta-band power. (D) Relative power in the five frequency bands. Error bars indicate SEM.
