The first human head transplant is planned for later this year and it looks one step closer as scientists report that they’ve successfully transplanted a smaller rat’s head onto another larger rat. The operation involved three rats in total: the donor, the recipient and a third used to maintain the blood supply to the transplanted head. After the operation, the rat whose head had been transplanted was able to see and feel pain, showing the brain was functioning despite having been detached from its original body.
Not all scientists are impressed with this path towards human head transplants: Hunt Batjer, the president elect of the American Association for Neurological Surgeons, has criticised the plans to transplant a human head. “I would not wish this on anyone,” he said. “I would not allow anyone to do it to me as there are a lot of things worse than death.”
