Anesthesia

How the brain loses and regains consciousnessStudy reveals brain patterns produced by a general anesthesia drug; work could help doctors better monitor patients.

Inside the unconscious brainNew study reveals brain-wave patterns that mark loss of consciousness during anesthesia.

Neuroscientists link brain-wave pattern to energy consumptionNew model of neuro-electric activity could help scientists better understand quiescent brain states such as coma.

How to reverse general anesthesiaNeuroscientists find that Ritalin could help bring surgical patients out of surgery much more quickly, with less grogginess.

Understanding the anesthetized brainNeuroscientist Emery Brown hopes to shed light on a longstanding medical mystery: how general anesthesia works.
