Figures & Tables

Figure 1.

Average relative power of EEG signals (delta, 0.5–4 Hz; theta, 4–8 Hz; alpha, 8–13 Hz; beta, 13–30 Hz; and gamma, 30–50 Hz) from all HCs and patients with MDD in the OE (A) and CE (B) condition. White circles denote significant differences between groups (P < 0.05). CE, eyes-closed; EEG, electroencephalogram; HCs, healthy controls; MDD, major depressive disorder; OE, eyes-open.
