A leading neurosurgeon has revealed a project to carry out the first human head transplantation with spinal linkage within the next two years. The project is code-named HEAVEN/GEMINI.
Published in the June issue of Surgical Neurology International, the project has been outlined by Italian neuroscientist and functional neurosurgeon, Dr. Sergio Canavero. He says the procedure would take 100 surgeons 36 hours to complete, and would cost around £8.5 million ($12.6 million).
In 1970, US neurosurgeon Robert Joseph White performed an operation to transplant a monkey's head onto another monkey's body. However, the inability to repair the severed spinal cord due to lack of required technology proved a problem, and the monkey was left paralyzed, passing away days later.
But Canavero believes today's technology will overcome this hurdle and refers to previous studies in which scientist have reconnected spinal cords to rats. Canavero explains that the transplant will work if surgeons can successfully link the spinal cord to the head by fusing severed axons, the nerve cells that transmit information to different neurons, muscles and glands.
In the paper, Canavero explains:
"The greatest technical hurdle to such endeavor is of course the reconnection of the donor's and recipient's spinal cords. It is my contention that the technology only now exists for such linkage."
He explains that cut axons can be reconstituted using molecules such as poly-ethylene glycol (PEG), used in many areas ranging from industrial manufacturing to pharmaceutical products. Another molecule that can be used is chitosan.
The surgery would involve putting the recipient's head into a "hypothermia mode" for around 45 minutes between 12°C and 15°C (the HEAVEN process). It is thought that this time frame would create virtually no neurological damage.
The GEMINI procedure would involve surgeons cutting the cooled spinal cords with an "ultra-sharp blade," before reconnecting the recipient's head to the donor body. In the paper, Canavero explains that this clean cut is the key to spinal cord fusion, as it allows the severed axons to be fused accurately with the molecules.
He explains that what is equally important is that the motorneuronal pools, responsible for the contraction of muscle fibers and skeletal muscle, remain fully intact so they can be engaged by spinal cord stimulation. Canavero says that this is a technique that has proven effective for motor control in patients with spinal injuries.
As the human brain can only survive without oxygen for one hour, the surgeons would have to remove both heads and connect the recipient's head to the circulatory system of the donor body within this time frame.
Canavero says that it is clear the procedure would extend some patients' lives and would be far-reaching. However, he says that a select group of gravely ill individuals would be the target, such as people with muscular dystrophies.
But he cautions that as the procedure is deployed within the clinical area, it needs proper regulation. He adds that a risk could develop whereby people with adequate funds try to secure the bodies of healthy young individuals on the black market and have them transplanted by dishonest surgeons - something he says needs to be addressed by society.

Old and fat people (like me) will be safe. People who look like Brad Pitt and Angelina Jolie will be in mortal danger.......
Paging C.S.Lewis, please pick up the smoking red phone!

I have had three serious operations, at various hospitals around the state. You'd be surprised.......especially when the bills come in from people you've never met........
The ‘procedure’ needs two living heads and two living bodies. Or one that died within the hour.
They are going to try it. There will be a lot of horrible failures before they reveal what they have done. They will hide those failures.
One question they haven’t answered. When the ‘living’ head says that the pain is too much, the horrible mismatch between the brain’s perceptions and the body’s is too much and asks to die, what will they do? Will they be tried for murder?
You can bet your sweet bippy that this guy is going to try it.
A body, sans head, can be kept 'alive' for quite a while through artificial means....
I think there is a point when people should quit while they’re a head.
ROFLMAO - my first time to see that movie a few weeks ago !!!
Rosie Grier was so funny in “The Thing With Two Heads”. When he shows up at his girlfriend’s place with an extra head, all she can say is,
“You get yourself into more s$#%....!”
Two heads are better than one............
I’m thinking Stephen Hawking’s head on the body of some athletic Hollywood celebrity who hasn’t done too many drugs.
For some real fun, they should graft a woman’s head onto a man’s body (or vice versa). How would you learn to use the other sex’s “parts”?
Transgender activists would be ecstatic............
