Selected brain wave connectivity features from the study using machine learning to distinguish between bipolar disorder and major depressive disorder. The electrodes highlighted with a bold black circle were used for recording the patients’ EEG signals. δ (1 Hz -3 Hz), θ (4 Hz–7 Hz), α (8 Hz–12 Hz), β (13 Hz–30 Hz), and γ (31 Hz–50 Hz) denote different frequency bands.
