of Course, the news is not coming from a scientific journal, as a specialist, but it is still shaking the wrists.
In the interview, Canavero summarizes the broad lines of a project published on Surgical Neurology International, an online magazine that instead focuses on neurosurgery. The project takes the name of HEAVEN/GEMINI, or Head Anastomosis Venture with Cord Fusion.
Canavero è già was the center of attention of the communityà scientific, to be able to ‘awaken’ in 2006, a patient in permanent vegetative state, restoring it to a state minimally conscious.
Now the neurosurgeon faces a challenge, that of the transplantation of the head, considered by many to be almost impossible for the technical problems that it presents. The impression, forò, è that will not only be the difficultyà techniques to overcome becauseé certainly the announcement will be followed by the controversy of an ethical order.
The Project is, in fact, founded the basis for the lengthening of the human life overcoming many moral barriers.
The true difficultyà an intervention of this type, according to the experts, is to continuityà of the reconstruction of the spinal cord.
Canavero explains, forò, the use of special chemical materials would restore the integrityà of a nerve fiber severed.
this Is thefusogeni‘, also called ‘sealing membrane’, from about 14 years of age the subject of experimentation in laboratories around the world, which would be effective for this purpose. That is the only one of the fuse together two sections of spinal cord from two different people, the body of the donor (without the head) with the stump of the neck of the person who receives it.
Canavero explains that the ideal donor is a person died of a head injury (stroke), provided that all the other organs have not been damaged.
To receive the body, on the contrary, the possible candidates may be the people tetraplegiche or patients affected by neuromuscular diseases degenerative diseases.
in Short, just talking about it is the desire to evoke scenes from sci-fi in which the very foundations of existence are being called into question.
Why is the same Canavero warned of the needà that “The company; it should già starting to think about how to regulate this procedure”.
The risk, according to the surgeon, is that “an intervention is revolutionary, designed to provide a radical therapy for sick people, deeply suffering, to become a practice much in the hands of surgeons without scruples”.
However, skepticism on the possibilityà to perform a transplant of the head seems già to come out. To speak of “pure science fiction” is; in fact, Giulio Maira, director of the institute of Neurosurgery of the Università’ Catholic.
To Maira, “There are technical problems enormous”, and adds that the neurosurgeon, you should not feed illusions, the scientific news are given with correctness and clarity, with no ads choc devoid of feedback.””
To experiment with the transplantation of the head, già in the ’70s, it was Robert Joseph White, a surgeon and american scientist became famous for his experiments on primates.
White, between the other catholic and a member of the Pontifical Academy of Sciences, run so usersì transplant of the head on the monkeys lives. The interventions succeeded, but with the disadvantage, however, provided, that the monkeys made were paralyzed from the neck downù.
