Inducing hibernation-like state in mice can protect organs during heart surgery

Researchers have developed a new method of protecting organs during heart and aortic surgery when blood circulation has to be blocked. Rather than relying on cold temperatures to induce hypometabolism and reduce the need for oxygen, the technique works by stimulating Q neurons in the brain, which slows metabolism down to a hibernation-like state. The findings could lead to new ways of performing similar surgeries in people.
