The head transplant has long been a goal of some on the outer edges of scientific research. (Oriana Fallaci profiled the main such controversial pioneer, Dr. Robert White, for Look in 1967.) Now a divisive surgeon, Dr. Sergio Canavero, believes that within two years he’ll be able to successfully transfer a human head from a shattered or dying body and graft it onto a donor body. Sure, if there was some safe way for Stephen Hawking or anyone similarly afflicted with a degenerative disease to have a new lease on life, that would be great, but it almost definitely won’t happen within Canavero’s timeframe and really shouldn’t happen anytime soon. We’re nowhere near close to being able to deal with such an operation, medically or ethically. From Ian Sample at the Guardian:

The Italian doctor, who recently published a broad outline of how the surgery could be performed, told New Scientist magazine that he wanted to use body transplants to prolong the lives of people affected by terminal diseases.

“If society doesn’t want it, I won’t do it. But if people don’t want it, in the US or Europe, that doesn’t mean it won’t be done somewhere else,” he said. “I’m trying to go about this the right way, but before going to the moon, you want to make sure people will follow you.”

Putting aside the considerable technical issues involved in removing a living person’s head, grafting it to a dead body, reviving the reconstructed person and retraining their brain to use thousands of unfamiliar spinal cord nerves, the ethics are problematic.

The history of transplantation is full of cases where people hated their new appendages and had them removed. The psychological burden of emerging from anaesthetic with an entirely new body is firmly in uncharted territory. Another hitch is that medical ethics boards would almost certainly not approve experiments in primates to test whether the procedure works.

But Canavero wants to provoke a debate around these issues. “The real stumbling block is the ethics,” he told New Scientist. “Should this surgery be done at all? There are obviously going to be many people who disagree with it.”•
