Several years ago, the news of the first human head transplant thundered all over the world. Italian surgeon Sergio Canavero announced that he was about to perform a similar operation
When Valery Spiridonov, a Russian disabled person with a crippled body, was named his patient, they began to talk a lot about such a procedure in our country.
True, later an unnamed Chinese man was chosen by the patient, and the timing of the operation itself was pushed further and further. Canavero transplanted heads to corpses and rats, but he still cannot get to an operation on a living person.
Technically, the matter does not seem particularly complicated, in the end, the heads of live dogs were transplanted by the Soviet doctor Demikhov. However, his dogs managed to live for the most part only a few days.
The main problem with completely cutting off the head and transplanting it to another body is the lack of normal technology for connecting the spinal cord. Without this, the head transplant patient will have no control over the muscles in the body. Technically, it could be kept viable with the help of apparatus, but it would rather be like torture.
In 2002, Japanese scientists seemed to have found the right solution to such a problem, they transplanted the heads of rats and they could control the body. The Japanese achieved this through the use of low temperatures, that is, by greatly cooling the head before transplantation, as well as through the technique of connecting nerve cells using polyethylene glycol.
However, if this is applied to a person, then his brain would have to be cooled to such a temperature at which all neural activity ceases. And this is fraught with new dangers.
However, if doctors learn to use the latest advances in stem cells, robotics and neural surgery for such an operation, then they may succeed in the next decade. I am sure of this Bruce Matthews - Former Lead Clinic at Kingston University Hospital in Yorkshire, England.
Matthews is also a writer and recently co-authored a science fiction novel "Chrysalis" with writer Michael J. Lee about the potential for human immortality. The idea that a human head transplant is not impossible, Matthews faced when he began to study this technology in detail as he wrote the novel.
"At first we just had a brainstorming session of various ideas, and at first it seemed pretty stupid, but then I realized that everything is really wrong and that if you separate the body from the head, and then attach the head to another body, then it is not impossible. This can be done in reality."
According to Matthews, for this, together with the head, the entire spinal nerve section can be transplanted into the new body, separating it from the spinal column.
"It is very difficult to extract the brain without drilling holes in the spine, but I am sure we will learn how to do this in the next 10 years."
Such an operation can help not only those wishing to become "immortal", but also people suffering from muscular dystrophy and other cripples.

Is Human Brain Transplant Possible?
People often ask the question: “Will there ever be an opportunity to transplant the human brain? And who will it be after the brain transplant - the person whose brain was taken as a transplant, or the person whose body received a new brain? " And finally, will the constant practice of brain transplant be the solution to the problem of the eternal life of the brain and human consciousness? Here's how scientists answer
Surgeons Confirm Human Head Transplant Is Possible
Surgeons Sergio Canavero and Ren Xiaoping confirmed the reality of a head transplant from Russian Valery Spiridonov. A physician from Italy spoke about this in an interview on the results of experiments on connecting the spinal cord in rodents and head transplantation in monkeys. “I am pleased to announce that we were able to respond to all the criticism that fell on us after and during the conference in Annapolis, when our colleagues expressed doubts that such operations are possible. Two peer-reviewed n
Russian Transplantologist: The Idea Of a Head Transplant Is Controversial, But Possible
Human head transplantation at the present stage of the development of medicine is technically possible, but this raises a number of questions of both ethical and methodological properties, Sergei Gauthier, director of the Federal Research Center for Transplantology and Artificial Organs, told RIA Novosti. Earlier in the media it was reported that the Italian neurosurgeon Sergio Canavero said that he would be able to carry out the first human head transplant in 2017. In his opinion, operations to change the head &
Russian Disabled Person Will Be The First To Receive A Head Transplant
In February 2015, physician Sergio Canavero published an article in the International Journal of Neurosurgery on the surgical operation of transplanting a human head onto a donor's body under hypothermic conditions. Valery Spiridonov, a thirty-year-old programmer from Russia, agrees to become the first person to undergo this operation. Valery suffers from spinal muscle atrophy, now he is communicating on Skype with Canavero and is preparing for a possible operation. In an interview with the Daily Mail, Valery said that the relationship
