"Ultrasound: Inducing Hibernation-Like State in Animals"
Researchers have used ultrasound to induce a torpor-like state in mice and rats, lowering their body temperature and metabolic rate. The ultrasound procedure activated neurons in the preoptic area of the brain, and a protein allowed ions to flow into and activate these neurons. While the effects were less pronounced in rats, the study marks the first successful induction of torpor-like effects in non-torpic animals. If proven effective in humans, this technology could have implications in treating patients who have experienced strokes or heart attacks by slowing their metabolism and minimizing damage.
