Despite the absence of responsiveness during anesthesia, conscious experience may
persist. However, reliable, easily acquirable and interpretable neurophysiological markers of …

Unconsciousness is a fundamental component of general anesthesia (GA), but
anesthesiologists have no reliable ways to be certain that a patient is unconscious. To …

Background How conscious experience becomes disconnected from the environment, or
disappears, across arousal states is unknown. We sought to identify the neural correlates of …

Neurophysiological markers can overcome the limitations of behavioural assessments of
Disorders of Consciousness (DoC). EEG alpha power emerged as a promising marker for …

Evidence suggests that the stream of consciousness is parsed into transient brain states
manifesting themselves as discrete spatiotemporal patterns of global neuronal activity …

Anesthetic-induced changes in the neural activity of the brain have been recently utilized as
a research model to investigate the neural mechanisms of phenomenal consciousness …

The mechanisms underlying anesthesia-induced loss of consciousness remain a matter of
debate. Recent electrophysiological reports suggest that while initial propofol infusion …

Significant changes in topographic quantitative EEG (QEEG) features were documented
during induction and emergence from anaesthesia induced by the systematic administration …

Background The bispectral index (BIS) and the spectral entropy (state entropy, SE, and
response entropy, RE) are depth-of-anaesthesia monitors derived from EEG and have been …

Background Burst suppression occurs in the EEG during coma and under general
anaesthesia. It has been assumed that burst suppression represents a deeper state of …
