You may well have spent hours wondering what your laptop could possibly be taking so much time over as it boots up, and now scientists have asked the same question of the human brain: How exactly does it start up again after being anesthetized, in
Millions of surgical procedures performed each year would not be possible without the aid of general anesthesia, the miraculous medical ability to turn off consciousness in a reversible and controllable way.
Credit: Jacob Dwyer, Michigan Medicine Millions of surgical procedures performed each year would not be possible without the aid of general anesthesia, the miraculous medical ability to turn off consciousness in a reversible and controllable way. Researchers are using this powerful tool to better understand how the brain reconstitutes consciousness and cognition after disruptions caused by sleep, medical procedures requiring anesthesia, and neurological dysfunctions such as coma. In a new study published in the journal eLife, a team led by anesthesiologists George Mashour, M.D., Ph.D. of Uni...
