Transplanting a human head onto a donor body may sound like the stuff of science fiction comics, but not to Italian doctor Sergio Canavero. He has not only published a paper describing the operation in detail, but also believes that the surgery could be a reality as early as 2017.

Canavero, Director of the Turin Advanced Neuromodulation Group, initially highlighted the idea in 2013, stating his belief that the technology to successfully join two severed spinal cords existed. Since then he's worked out the details, describing the operation in his recent paper, as the Gemini spinal cord fusion protocol (GEMINI GCF).

To carry out the transplant, a state of hypothermia is first induced in both the head to be transplanted and the donor body, to help the cells stay alive without oxygen. Surgeons would then cut into the neck tissue of both bodies and connect the blood vessels with tubes. The next step is to cut the spinal cords as neatly as possible with minimal trauma.

The severed head would then be placed on the donor body and the two spinal cords encouraged to fuse together with a sealant called polyethylene glycol, which Canavero notes in his paper, has "the power to literally fuse together severed axons or seal injured leaky neurons."

After suturing the blood vessels and the skin, the patient is kept in a comatose state for three to four weeks to discourage movement and give both spinal stumps time to fuse. The fusion point will also be electrically stimulated to encourage neural connections and accelerate the growth of a functional neural bridge. The patient will additionally be put on a regime of anti-rejection medications.

According to Canavero, with rehabilitation the patient should be able to speak in their own voice and walk within a year's time. The goal is to help people who are paralyzed, or whose bodies are otherwise riddled with degenerative diseases and other complications. While the procedure sounds extremely complex and disturbing on multiple levels, Canvero tells us he's already conducting interviews with volunteers who've stepped forward.

"Many are dystrophic," Canavero tells Gizmag. "These people are in horrible pain."

The most well-known example of a head transplant was when Dr. Robert White, a neurosurgeon, transplanted the head of one rhesus monkey onto another in 1970. The spinal cords, however, were not connected to each other, leaving the monkey unable to control its body. It subsequently died after the donor body rejected the head.

Current technology and recent advances hold out more promise. Canavero plans to garner support for the project, when he presents it at the American Academy of neurological and Orthopaedic Surgeons conference in Annapolis, Maryland, later this year. Understandably his proposal has generated incredible controversy, with experts questioning the specifics and ethics of the procedure, even going as far as calling it bad science.

Canavero isn't fazed at all, though.

"These experts failed for 35 years to cure paralysis," Canavero tells us. "Pretty sure the bad science is theirs."

The study describing GEMINI GCF was published in the journal Surgical Neurology International, linked below.

If I'm going to have my head transplanted, I wouldn't want another human body. I'd want a robot body. Better, stronger, faster.

@Gadgeteer honestly i'd want a genetically modified/improved clone of my own body. that's assuming they will learn how to grow a clone body without the head, for ethical reasons. I'm ok with implants and nanotechnology, but a fully robot body isn't desirable to me right now. I like the human body, i like eating food, and all the other pleasant things that come with being made of wetware. These head transplants have some radical life extension potential.
It's being developed to help people with serious medical mobiilty conditions, but we know who will be first in line for a life extension...
But work out the kinks with the paralyzed patients first.
Bonding two different severed spinal chords with an adhesive (or whatever) is probably the greatest challenge, but for the foreseeable future, the plebes who don't want to die will have to settle for a cyborg setup, since religion doesn't cut it anymore.
I'm thinking that it's not going to be easy to find a supply of donor bodies. Any volunteers?

Nope, don't like it one bit. Just too crazy.
interesting - well that should answer the question of whether all our intelligence and knowledge REALLY is held in our brain tissue - THAT question is still not answered completely - so wonder what 'extra' stuff one might acquire via a new body ? I can understand someone being sufficiently desperate to try this if they have a useless/painful body.

Great. I've been looking for a way to get ahead.

There can be no such thing as a head transplant - it's a body transplant. Transplants are done from the perspective of the recipient and the recipient is the [person inside the] head.
