Evaluation of putative signatures of consciousness using specific definitions of responsiveness, connectedness, and consciousness
Authors' conclusion
None of the proposed EEG-based neural correlates of unresponsiveness corresponded solely to consciousness, highlighting the need for a more conservative use of the term (un)consciousness when assessing unresponsive participants.
Study context
- Population
- Unresponsive subjects during dexmedetomidine or propofol sedation or natural sleep
- Comparison
- Resting-state EEG measures across connected consciousness, disconnected consciousness and unconsciousness
Primary result
As reported in the abstract
Association of 10 published resting-state EEG measures with consciousness vs connectedness
- Disconnected consciousness to unconsciousness: significant decreases in permutation entropy and spectral exponent
- P<0.05
