Neural activity patterns stabilize during wakefulness and conscious experience.

Summary
A new pre-registered study in PLOS Biology compares several proposed neuronal markers of loss of consciousness in flies across three global brain states: awake, asleep, and anesthetized. The work evaluates which neural markers can differentiate these states, testing markers previously suggested to underlie states of consciousness. The findings indicate which markers reliably distinguish between wakefulness, sleep, and anesthesia in the fly model.

Abstract
Several neuronal markers have been proposed to differentiate the global brain states that underly states of consciousness. A new pre-registered study in PLOS Biology compares neural markers of loss of consciousness in flies when awake, asleep, and anesthetized.
