The Story of the First Human Head Transplant Won't Die (theoutline.com)
Stories about the first human head transplant operation, supposedly coming in December 2017, are circulating again. From a report on the Outline: But despite what you might have read or seen, humanity is not much closer to transplanting a human head to a new body than we were last year. Sorry to disappoint anyone looking to get their head transplanted. The story is based on the work of one man: Italian neurosurgeon Sergio Canavero. Canavero started making headlines in 2013 with ambitious claims about the process he designed for a transplant of a human head -- as in, moving a healthy human head from a subject with an unhealthy body to an otherwise-healthy, brain-dead donor body. Canavero's claims have been alternately regarded as sensationalist, spurious, and ethically murky. Since then, the doctor has periodically resurfaced in the news. Once, when he found a willing patient in Valery Spiridonov, a Russian man with spinal muscular atrophy in the form of Werdnig-Hoffmann disease; other times when he published papers, including two proof-of-principle studies last year as well as articles reviewing preliminary work on animals relating to his proposed procedure. Though published in the internet-only journal Surgical Neurology International, an important distinction here is that none of these actually involve a successful full transplant of any kind despite his claim to have successfully transplanted a monkey's head. The papers addressing work with animals are, broadly speaking, about treating spinal cord injuries and issues. -

Surgeon: First Human Head Transplant May Be Just Two Years Away
HughPickens.com (3830033) writes "Michelle Star writes at C/net that Surgeon Sergio Canavero, director of the Turin Advanced Neuromodulation Group in Italy, believes he has developed a technique to remove the head from a non-functioning body and transplant it onto the healthy body. According to Canavero's paper published in Surgical Neurology International, first, both the transplant head and the donor body need to be cooled in order to slow cell death. Then, the neck of both would be cut and the major blood vessels linked with tubes. Finally, the spinal cords would be severed, with as clean a cut as possible. Joining the spinal cords, with the tightly packed nerves inside, is key. The plan involves flushing the area with polyethylene glycol, followed by several hours of injections of the same, a chemical that encourages the fat in cell membranes to mesh. The blood vessels, muscles and skin would then be sutured and the patient would be induced into a coma for several weeks to keep them from moving around; meanwhile, electrodes would stimulate the spine with electricity in an attempt to strengthen the new nerve connections.
Head transplants has been tried before. In 1970, Robert White led a team at Case Western Reserve University in Cleveland, US, that tried to transplant the head of one monkey on to the body of another. The surgeons stopped short of a full spinal cord transfer, so the monkey could not move its body. Despite Canavero's enthusiasm, many surgeons and neuroscientists believe massive technical hurdles push full body transplants into the distant future. The starkest problem is that no one knows how to reconnect spinal nerves and make them work again. "This is such an overwhelming project, the possibility of it happening is very unlikely," says Harry Goldsmith." -
Neuroscientist: First-Ever Human Head Transplant Is Now Possible
dryriver writes "Technical barriers to grafting one person's head onto another person's body can now be overcome, says Dr. Sergio Canavero, a member of the Turin Advanced Neuromodulation Group. In a recent paper, Canavero outlines a procedure modeled on successful head transplants which have been carried out in animals since 1970. The one problem with these transplants was that scientists were unable to connect the animals' spinal cords to their donor bodies, leaving them paralyzed below the point of transplant. But, says Canavero, recent advances in re-connecting spinal cords that are surgically severed mean that it should be technically feasible to do it in humans. (This is not the same as restoring nervous system function to quadriplegics or other victims of traumatic spinal cord injury.)"
