Head transplant is a surgical operation which involves the point of insertion of a one organism's head onto the body of another, including brain.
Head transplants have been successfully performed on dogs and monkeys by surgeons.
In 1970, a first head transplant successfully moves out on a monkey, but unfortunately it was dying after the head was rejected by the body's immune system, and another reason is technology. Lately, this transplant seemed totally doubtful.
Italian neurosurgeon Sergio Canavero announced his plans to perform the first human head transplant, means to putt an entire head on a new body. The procedure of transplant estimates to take 100 surgeons nearby 36 hours long journey to complete the process, and estimates that the cost of operation is $10million.
Three years ago, he announced a human head transplant in a two modules, HEAVEN (head anastomosis venture) and GEMINI (subsequent spinal cord fusion).
Valery Spiridonov, a 30-year-old Russian man, who has a rare genetic disorder called Werdnig-Hoffmann disease, in which motor neurons in the spinal cord and the brainstem gradually die, resulting in shrinking muscles and paralysis. He was a first person to volunteer for the procedure.
The procedure will involve spinal cord fusion (SCF). The head will be attached to the donor body are first cooled down to 12-15˚C to ensure that the cells last longer than a few minutes without oxygen. Using a sharp blade to cut the tissue around the neck in order limit the amount of damage the spinal cord sustains.
Canavero suggests that, the spinal cord of the donor body will be fused using a chemical called polyethylene glycol, it promotes nerve growth in the spinal cord, and it could be used as a sort of glue between the body and head.
Some experts have pointed out the proposed surgery, Dr. Christopher Winfree, assistant professor of neurological surgery at Columbia University said, A fancy glue is not going to fix that, even if you could get them physically, nerves themselves don’t grow too much in the spinal cord.
Canavero explains, the patient will be kept in a coma for a month, during the time spinal cord will be subject to electrical stimulation via implanted electrodes in order to boost the new nerve connections.
Gordon R. Tobin, M.D. Professor of Surgery and Chief of Plastic and Reconstructive Surgery, University of Louisville said, nerves did not function as we planned, and that was just a few of them. Neurosurgeons just don’t know enough about the brain yet to even know what they need to connect. It’s hard to solve the problem if you don’t even know what that problem is.
So, the transplant will take place by the end of 2017, and the surgery runs at Harbin Medical University in china.
