Using EEG data as a biomarker unrelated to sleep sounds interesting. From the paper [1]: > At the baseline and week 8 clinic visits, the severity of the participant’s depressive symptoms was rated on the 21-symptom HRSD... > In addition, electrophysiological measures were also acquired; resting-state EEG was recorded for 2 minutes while participants were relaxed with eyes closed and eyes open. > Electroencephalograms were continuously recorded from 26 sites in 5 regions (frontal, temporal, central, parietal, and occipital) with a NuAmps system (Compumedics) and QuickCap (Compumedics). For each site, we computed absolute and relative band powers for the delta, theta, alpha, beta, and gamma bands.
