No Brain-Damaging Blood Loss <\/p>\n
Okay, so its 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. <\/p>\n
Now, scientists from China have made a remarkable breakthrough intransplanting the head of one organism onto that of another. <\/p>\n
For their work, they took the head of a smaller ratand attached it to abigger 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 teamknew 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. <\/p>\n
However, this is an astonishing step forward in performing viable head transplants in that the doctorswere able toavoid any brain-damaging blood loss while the donors head was being attached. <\/p>\n
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 donorrats blood vessels to the other rat. <\/p>\n
We developed a bicephalic model of head transplantation to study these aspects, the scientists report inthe paperthat they published in the journal CNS Neuroscience and Therapeutics. <\/p>\n
While the idea is a real head turner and maybe a head shaker, for some scientists assert that head transplants areworth exploring, as it could help millions of people worldwide who are suffering from muscle or nerve problems. It could also allow us to take the head of a person suffering from fatal cancer and transplant it onto a healthy human body. <\/p>\n
Understandably, there are a number of issues that have to be resolved before it would be possible to transplant human heads. For example, apart from making sure the brain isnt damaged by blood loss during the transplant process, there are a number of other concerns, such as rejection by the immune system. <\/p>\n
Still, grafting a head onto another while keeping the brain safe from the damage associated with blood loss is certainly a positive step forward as far asdeveloping a viable means of conductinghuman head transplants. <\/p>\n
However, some experts assert that the problems associated with transplanting human heads extend beyond scientific and technical concerns and touch upon the fundamental nature of human psychology. <\/p>\n
Arthur Caplan, founding director of NYULMCs Division of Medical Ethics, previously told Futurism that, in such a procedure, a person could suffer from unprecedented levels of insanity. He ultimately stated that this would likely result from things such as novel chemistry flooding the brain, unfamiliar input coming in from the nervous system of the body, etc. <\/p>\n
While some claim to have already successfully performed the procedure, theres no clear evidence to supportsuch claims. <\/p>\n
In any case, if we are to ever successfully completesuch a procedure in the future, this most recent study provides an important piece of the puzzle. As the researchers note in their abstract, The application of vascular grafting can also provide the possibility of long-term survival of the model. <\/p>\n
