London: The scientist who claims to be about to carry out the first human head transplant says that he has successfully done the procedure on a monkey.
Maverick neurosurgeon Sergio Canavero has tested the procedure in experiments on monkeys and human cadavers, he told New Scientist.
Dr Canavero says that the success shows that his plan to transplant a human’s head onto a donor body is in place. He says that the procedure will be ready before the end of 2017 and could eventually become a way of treating complete paralysis.
“I would say we have plenty of data to go on,” Canavero told New Scientist. “It’s important that people stop thinking this is impossible. This is absolutely possible and we’re working towards it.”
The team behind the work has published videos and images showing a monkey with a transplanted head, as well as mice that are able to move their legs after having their spinal cords severed and then stuck back together.
Fusing the spinal cord of a person is going to be key to successfully transplanting a human head onto a donor body. The scientists claim that they have been able to do so by cleanly cutting the cord and using polyethylene glycol (PEG), which can be used to preserve cell membranes and helps the connection recover. The monkey head transplant was carried out at Harbin Medical University in China, according to Dr Canavero.
The monkey survived the procedure “without any neurological injury of whatever kind,” the surgeon said.
