Anesthesia’s effect on consciousness solved, settling century-old scientific debate

Exposure to anesthesia causes lipid clusters to move from an ordered state to a disordered one, then back again. These changes lead to subsequent effects that cause changes in consciousness.

How our brain generates consciousness; and loses it

Medically induced loss of consciousness disrupts neuron population activity patterns by generating fewer discriminable network microstates, and fewer neuronal ensembles. Findings suggest local neuronal ensemble dynamics may contribute to the emergence of conscious states.

General anesthesia hijacks sleep circuitry to knock you out

Study reveals anesthesia activated neurons have been discovered in the hypothalamus. Activation of AANs promotes slow-wave sleep, extending the effects of anesthesia, while inhibition of AANs shortens the duration of general anesthetics and disrupts natural sleep.

Caffeine Shortens Recovery Time From General Anesthesia

A new study reveals animals injected with caffeine during the last 10 minutes of exposure to general anesthetic woke more quickly than those injected with saline solution. Waking times became significantly quicker with higher doses of caffeine.
