 Researchers at the University of Texas's Southwestern Medical Center developed a device that can isolate blood flow to the brain, which could keep the brain organ alive and functioning independent from the rest of the body for several hours. In an animal model using anesthesia, the researchers redirected the brain's blood supply through a pump that maintained or adjusted a range of variables like blood pressure, volume, temperature, oxygenation, nutrients. Over five hours, the team found that the brain activity and other measurements had minimal to new changes.
