Scientists Transplanted A Rat's Head Onto Another Rat, Hoping to Replicate It in Humans

Okay, so it’s not every day you hear about a real life head transplant, but there is such a thing. In fact, research into transplanting heads has been around for a while now, with the first known two-headed animal experiments dating as far back as the 1900s and the 1950s. Now, scientists from China have made a remarkable breakthrough in transplanting the head of one organism onto that of another. For their work, they took the head of a smaller rat and attached it to a bigger one, creating what is effectively a two-headed rat. It is important to note that the rat did not survive long-term, but that was never the goal. The team knew the rat would not live long, as there are still a lot of technical and scientific issues that need to be resolved before we can successfully perform head transplants on living organisms and have them survive. It also provides the possibility of long-term survival. However, this is an astonishing step forward in performing viable head transplants in that the doctors were able to avoid any brain-damaging blood loss while the donor’s head was being attached. The goal of this particular experiment was simple: the scientists wanted to know if they could successfully transplant a head without damaging the brain due to excessive blood loss. And they did. To do this, they had to keep the blood circulation going during the transplant by attaching the donor rat’s blood vessels to the other rat. “We developed a bicephalic model of head transplantation to study these aspects,” the scientists report in the paper that they published in the journal CNS Neuroscience and Therapeutics.
