Italian surgeon Sergio Canavero is fully confident that he can transplant a human head on another human body. World didn’t give much attention to this claim until now. But recently he got a patient who is ready to transplant his head to another body.
A Russian Computer expert Valery Spiridonov, who is
wheelchair bound due to a muscle-wasting disease, Werdnig-Hoffmann disease,
which will one day kill him, announced he would be the first volunteer to
undergo a head transplant.
In the modern history biologists and physicians have mad
attempts to transplant the head of living organisms. They have tried it with dogs, monkeys, mice
etc. Even though there was a limited
success at the initial stage, to say they were able to prolong the death for
some hours or days. But fallen long way
back in the road to have successful transplantation.
In short the head transplantation requires the cutting of
the head of both the recipient and the donor at the same time with a blade of
immense speed. All blood vessels and
nerves has to be connected with the head and recipients body. The supply of
blood to the brain should not be stopped for a fraction of a second. Similarly all the organs should keep intact
until the recovery. It require the
service of around 150 surgeons and scores of nursing and para medical staff.
According to books “Doctors have never successfully
reconnected a fully detached spinal cord. For a completely severed spinal cord
to be brought back to functionality there are millions of nerve connections
that need to be linked back together, and these are wildly difficult to rejoin.”
It's also possible that, due to biochemical differences
between the head and the donor body, the person would probably never be able to
regain normal consciousness.
Dr Hunt Batjer, president of the American Association for
Neurological Surgeons, said: "I would not wish this on anyone.
"I would not
allow anyone to do it to me as there are a lot of things worse than death."
