The role of the prefrontal cortex (PFC) in the mechanism of consciousness is a matter of
active debate. Most theoretical and empirical investigations have focused on whether the …

Sleep is a universal, essential biological process. It is also an invaluable window on
consciousness. It tells us that consciousness can be lost but also that it can be regained, in …

The human brain displays a rich repertoire of states that emerge from the microscopic
interactions of cortical and subcortical neurons. Difficulties inherent within large-scale …

Establishing the neural mechanisms responsible for the altered global states of
consciousness during anesthesia and dissociating these from other drug-related effects …

In the field of consciousness science, there is a tradition to categorize certain states such as
slow-wave non-REM sleep and deep general anesthesia as “unconscious”. While this …

Background Understanding the neural correlates of consciousness has important
ramifications for the theoretical understanding of consciousness and for clinical anaesthesia …

Electroencephalography (EEG) is a technique for non‐invasively measuring neuronal
activity in the human brain using electrodes placed on the participant's scalp. With the …

In a recent electroencephalography (EEG) sleep study inspired by complexity theories of
consciousness, we found that multi-channel signal diversity progressively decreased from …

The neural mechanisms through which individuals lose sensory awareness of their
environment during anesthesia remains poorly understood despite being of vital importance …

The optimal consciousness level required for general anesthesia with surgery is unclear, but
in existing practice, anesthetic oblivion, may be incomplete. This article discusses the …
