Under propofol general anesthesia very slow frequency traveling waves transform and dominate, redirecting and disrupting the higher frequency traveling waves associated with conscious function. Under ...

Under propofol general anesthesia, sensory input still reaches the brain, but signals do not spread. A new study suggests consciousness requires cortical regions to all be 'on the same page.' General ...

Older patients who received anesthesia with etomidate had no higher risk of major complications after elective abdominal surgery compared to propofol, a randomized trial found. Among 1,917 such ...

Orexinergic neurons are inhibited by propofol anesthesia and the orexin signals are involved in arousal regulation from propofol, according to an article in Anesthesia & Analgesia. Previous studies ...

A study published in the May issue of Anesthesiology found that methylphenidate enables rats to wake more quickly following a single dose of propofol and also induces emergence during continuous ...

General anesthesia evokes a dual mystery: How does it disrupt consciousness, including sensory perception, and what might that say about the nature of consciousness. A new study led by researchers at ...

Scientists from Harvard University and Massachusetts General Hospital studied a hypothesis that anesthesia drugs bring about sedation by causing different parts of the brain to lose functional ...
