EEG Connectivity is an Objective Signature of Reduced Consciousness and Sleep Depth
Brain Topography September 5, 2025 Toedt Inken, Gesine Hermann, Enzo Tagliazucchi et al.
Different levels of reduced consciousness characterise human sleep stages at the behavioural level. On electroencephalography (EEG), the identification of sleep stages predominantly relies on localised oscillatory power within distinct frequency bands. Several theoretical frameworks converge on the central significance of long-range information sharing in maintaining consciousness, which...
