Analogous cortical reorganization accompanies entry into states of reduced consciousness during anesthesia and sleep.

Cerebral Cortex August 23, 2023 Bryan M Krause, Declan I Campbell, Christopher K Kovach et al.

Theories of consciousness suggest that brain mechanisms underlying transitions into and out of unconsciousness are conserved no matter the context or precipitating conditions. We compared signatures of these mechanisms using intracranial electroencephalography in neurosurgical patients during propofol anesthesia and overnight sleep and found strikingly similar reorganization of human cortical...

Cortical functional connectivity indexes arousal state during sleep and anesthesia.

Neuroimage May 1, 2020 Matthew I Banks, Bryan M Krause, Christopher M Endemann et al. 78 citations

Disruption of cortical connectivity likely contributes to loss of consciousness (LOC) during both sleep and general anesthesia, but the degree of overlap in the underlying mechanisms is unclear. Both sleep and anesthesia comprise states of varying levels of arousal and consciousness, including states of largely maintained conscious experience (sleep: N1, REM; anesthesia: sedated but responsive)...
