Anesthesia Awareness
A universal signature could make surgeries safer — and help reveal what holds consciousness together.
After the trauma of a high-risk medical procedure, Eric Markowitz discovered a kind of consciousness that lives not in thought — but in presence.
"The amount of interest is enormous," says anesthesiologist Boris Heifets. "People are dropping in and coming out of the woodwork, trying to understand how to do this."
Propofol, a drug commonly used for general anesthesia, derails the brain’s normal balance between stability and excitability.
Anesthesia causes animals and humans to lose consciousness. A study found it has a similar effect on Venus flytraps.
“At that time, it was just a wild idea, [...] that instead of just a loss of consciousness, anesthetics may do something to the brain that actually turns pain off.”
