Is the world s first head changer still alive, and is the world s first head changer alive?

The world is full of wonders, with the development of life science and technology, people can choose more and more in life, in the past era, what everyone is pursuing is immortality, but you must know that everyone is born can not escape the level of birth, old age, sickness and death, and the most commonly used method in ancient times is to cultivate pills to live forever. In ancient times, the most common method was to cultivate pills to live forever, and now, they will prolong their life by exchanging hearts, and then some people have asked, now that science and medicine are so developed, can it be exchanged for heads?

For this problem, in fact, this experiment was done in a foreign country a long time ago, his name is Valery Donov, he is a famous computer expert, because he has suffered from muscular dystrophy since childhood, the more he grows up, the more his body will be under his control, until he is paralyzed and unable to move, only his own head is normal.

Later, he thought of transplanting his head to someone else to continue his life, and he was one of the lucky ones, as a young Russian man who was about to die due to brain necrosis donated his body to Valéry.

For this operation, there was no such superb medical skill at that time, and I happened to learn that a superb neurologist in Italy, named Sergio Tanavero, was about to prepare for the operation on Valéry, and then Valéry lying on the operating table suddenly became afraid, he recalled that he said that the operation was not very sure that he would be successful, and then after a few minutes of ideological struggle, he proposed that he did not want to do this operation.

And the person who really achieved the success of the head replacement surgery was actually in Harbin. At that time, it took 18 hours for a living person to perform a head swap operation with a dead person. In terms of expenses, it soared to about 70 million in an instant.

As a bystander, I naturally don't know whether this matter is true or false.

Hello, I want to change my head** can be changed.

The world's first head changer is dead.

Canavero, a surgeon at the Advanced Society of Neuromodulation in Turin, Italy, has recently proposed a whole-body transplant, in which a patient's head is transplanted into a new body to give it a "new body". The world's first human body-swapping surgery will begin as soon as next year, and the protagonist is 30-year-old Russian computer engineer Spiridonov.

According to the report, Spiridonov was born with spinal muscular atrophy, and his muscles stopped developing, leaving him with a total disability and skeletal deformities since he was a child. Two years ago, he turned to Canavero for a healthy body transplant and expected surgery as soon as next year, but the two have only been in contact via email and online phone calls, and have never met in person.

Head replacement surgery: As we all know, our people's deaths are often due to the aging of some organs of the body, which leads to slow metabolism and then loses the function of the organs, leading to the death of the human body. If some aging organs are replaced, just like replacing aging machine parts, a person's life can be prolonged.

At present, there are many successful cases of heart, liver, and kidney transplantation.

In addition to the transplantation of these organs, head replacement surgery has also emerged. It is well known that the human body dies once the head leaves the body. In ancient times, death row prisoners were beheaded.

There are not only many nerves and blood vessels in the head, but also bone marrow that connects to the body, and the slightest carelessness can lead to death. Therefore, head replacement surgery is much more difficult than other organ transplants.

The world's first person to change his head did not survive, and the physiological and ethical issues involved in the operation are very complex, and there are also very high technical requirements, and this technology has not yet been successfully applied to humans.

In fact, the so-called successful "head swapping" that has been hyped up in the past two days was carried out on corpses, that is, the head of one dead body was attached to the body of another dead body. Perhaps this is indeed a breakthrough attempt, but it is still far from being successful in changing heads on living people. To date, in vivo head-swapping experiments have been conducted on animalsAnd never really succeeded

What happened to the animals that were replaced? In the 50s of the 20th century, the former Soviet scientist Vladimir Demikhov conducted 24 experiments on dog head transplantation, but each time the dog died shortly after the operation. After the operation, it went through 4 days of two-headed life and then died.

The reason why it is difficult to change the head is mainly due to the following three reasons: the brain needs to be frozen to 12-15, and not all brains can survive at such temperatures. Columbia Assistant Professor of Neurosurgery said

If you do this on 10 people, only 3 to 4 people's brains will survive. "It's hard to reconnect a completely detached spinal cord Doctors have never succeeded in reconnecting a completely detached spinal cord, and when a spinal cord is completely severed, we want him to reconnect and regain function, and millions of nerves need to be connected, which is very difficult. Spinal cord fusion has not even been experimented with in animals. Rejection is when the body perceives a new part as foreign and attacks it.

The rejection caused by "head swapping" is one of the reasons for the rapid death of experimental animals, and when a new, intact head is presented, many organs in the body are considered foreign.

In fact, it is very difficult to connect even the head and body of the same person。In recent years, doctors have "rejoined" a severely damaged spinal cord in a small child, but note that it is "injury" rather than "complete severance", and that there is still enough connection between the spinal cords. In addition, the nervous system of young children is still developing, which can compensate for the damage.

Even so, such a successful surgery is quite difficult, let alone connecting the heads and bodies of different people.

When it comes to "head replacement" surgery, will you feel a chill in your neck, the head can be said to be a particularly important part of our human body, after all, our brain is here. Achieving a "head replacement" surgery is bound to take a lot of risk.

With the development of science and technology, scenes that can only be seen in science fiction movies in the past are gradually being realized, such as organ transplantation, which is now a very common operation, but for head transplantation, it seems like a fantasy. But recently, some scientists claimed to have completed the world's first human head replacement surgery.

Cannavaro said that what everyone thought was impossible is happening now. He said that the experiment**, including the surgical procedure and the timetable for the transplant, will be announced within a few days to provide sufficient evidence that the surgery is authentic and reliable.

I don't think it has been reported in normal reports yet, so I don't think there are any successful cases.

Spiridonov, a Russian suffering from spinal muscular atrophy, performed the first head replacement operation.

Two years ago, Italian neurosurgeon Sergi Cannavaro announced that the first human head transplant would be completed within two years.

The surgery means that the brain needs to be frozen to 12-15, and at this temperature, not all brains will survive.

When you have a new, intact head, many of the organs in your body are considered foreign.

An assistant professor of neurosurgery at Columbia said: "If you do this in 10 people, a lot of the organs in your body will be considered foreign.

The two corpses have been successful, and the living have not been officially replaced!

No. But every time the dog dies shortly after the operation. After the operation, it went through 4 days of two-headed life and then died.
