Longitudinal changes in EEG metrics. A) The ratio between α and θ amplitude increases with level of consciousness, and shows an overshoot for the patients with higher levels of consciousness. The number of measurements per level of consciousness is indicated by n. B) β amplitude increases with level of consciousness. C) θ connectivity shows an inverted-U relationship with level of consciousness. Controls are shown for visual comparison. Error bars denote the SEM. PALOC-s: Post-Acute Level of Consciousness scale.
