State-dependent, frequency-specific modulation of electrocortical traveling waves by anesthesia

This study examines how anesthesia affects cortical traveling waves across different states, finding frequency-specific changes and a paradoxical state resembling wakefulness during deep anesthesia.

Reorganization of Human Brain Waves Across Diverse States of Consciousness

This study identifies four wave propagation motifs in the human brain across different states of consciousness and shows how they reconfigure in diminished and psychedelic states.

Dynamic electrocortical states and paradoxical complexity during desflurane anesthesia

This study identifies seven cortical states during desflurane anesthesia, revealing a paradoxical activated state with increased complexity during deep anesthesia.

Regulation of REM Sleep Onset and Homeostasis by Preoptic Glutamatergic Neurons

This study investigates the role of preoptic glutamatergic neurons in REM sleep regulation, finding they suppress REMs and disrupt sleep homeostasis when activated.

Urethane Anesthesia Exhibits Neurophysiological Correlates of Unconsciousness and is Distinct from Sleep

This study compares electroencephalographic signatures of urethane anesthesia and natural sleep-wake states in rats, finding distinct neurophysiological features in urethane that differentiate it from sleep.

Recovery of Consciousness and Cognition after General Anesthesia in Humans

This study investigates recovery of consciousness and cognition after general anesthesia in humans, finding that executive function recovers before other cognitive domains and frontal cortical activity recovers faster than posterior.

Glutamatergic neurons in the preoptic hypothalamus promote wakefulness, destabilize NREM sleep, suppress REM sleep, and regulate cortical dynamics

Correlation between the epigenetic modification of histone H3K9 acetylation of NR2B gene promoter in rat hippocampus and ethanol withdrawal syndrome

This study shows that histone H3K9 acetylation of the NR2B gene promoter and NR2B expression levels are positively correlated with ethanol withdrawal syndrome in rat hippocampus.

Differential role of prefrontal and parietal cortices in controlling level of consciousness

The paper shows that cholinergic stimulation of the prefrontal cortex restores wakefulness in anesthetized rats, while noradrenergic stimulation does not.
