A new study of neural oscillations during varying stages of consciousness shows that anesthesia doesn’t just knock us out—it ...

An advanced closed-loop anesthesia delivery system that monitors brain state to tailor propofol dose and achieve exactly the desired level of unconsciousness could reduce post-op side effects. If ...

More than providing a good readout of unconsciousness, Brown added, the new algorithms offer the potential to allow anesthesiologists to maintain it at the desired level while using less drug than ...

Machine learning software advances could help anesthesiologists optimize drug dose, potentially improving patient outcomes. Anesthestic drugs act on the brain but most anesthesiologists rely on heart ...

There are many drugs that anesthesiologists can use to induce unconsciousness in patients, but exactly how these drugs cause the brain to lose consciousness has been a longstanding question. A study ...

ANN ARBOR, Mich. - When patients undergo major surgery, they're often put under anesthesia to allow the brain to be in an unconscious state. But what's happening in the brain during that time? Three ...

A figure from the paper summarizes the main findings. Under either ketamine or dexmedetomidine general anesthesia, brain waves become shifted out of phase within a hemisphere and more into phase ...

In a uniquely deep and detailed look at how the commonly used anesthetic propofol causes unconsciousness, a collaboration of labs at The Picower Institute for Learning and Memory at MIT shows that as ...

The human brain is the only reason our species has survived on this planet for so long, but even it has a blind spot. When it’s unconscious — whether because of sleep, anesthesia, or a coma — we’re ...

When we are unconscious, our brains experience a communication breakdown. Whether you're sleeping, under anesthesia or in a coma, unconsciousness is rooted in how different areas of the brain become ...
