General anaesthesia is physiologically distinct from natural sleep
the verdict
SUPPORTED
the evidence backs this
confidence 92/100
General anaesthesia is physiologically and neurophysiologically distinct from natural sleep, characterized by unique patterns of functional connectivity, spectral properties, and neural network breakdowns.
