Italian neurosurgeon Sergio Canavero claimed on Friday that he
had accomplished the world’s first human head transplant between two
corpses — however gave no proof to again it up.
At a press convention in Vienna, Austria, Canavero introduced that
he had eliminated the top from one corpse and connected it to
the physique of one other corpse by fusing the backbone, nerves, and blood
vessels. He mentioned he then stimulated the nerves of the corpse that
had undergone the process to see if it “worked.”
“The first human transplant on human cadavers has been
finished,” Canavero mentioned in a video of
the convention that he posted to Facebook. He claimed the
process lasted 18 hours and mentioned the subsequent “imminent” step would
be to do the process on a residing human paralyzed from the neck
Canavero launched no particulars in regards to the process, comparable to
whether or not the cadavers had their organs eliminated or if any
sort of supportive gear was used to maintain them. Instead he
advised reporters scientific paper with the small print could be
launched within the “next few days.”
Canavero ultimately plans to do an identical surgical procedure on residing
When Canavero has mentioned his plans for these kinds of
procedures up to now, he has referred to the method as a
head transplant or a “full body transplant.” But he described his
newest work in another way.
“My main purpose was not a head transplant. My main purpose was a
mind transplant,” Canavero mentioned on Friday.
defined it to Business Insider in July, the process he
ultimately needs to finish — no matter its title — will contain
going into the spinal wire of somebody with a spinal damage and
slicing out the injured segments of the wire. The donor’s wire
could be lower to completely change the lacking portion within the
injured individual. Then the 2 wholesome stumps could be fused
Canavero plans to connect the cords utilizing polyethylene glycol
(PEG), a typical laboratory instrument used to encourage cells to fuse.
Canavero merely refers to it as “glue.”
He mentioned on the time that he would quickly full this transplant
process with two people — a Chinese nationwide who stays
nameless and a brain-dead organ donor. The head of the
former could be connected to the physique of the latter, he
“By October you will know every single thing from China,” he advised
Business Insider on the time.
On Friday, he mentioned the process between corpses proved that the
process had been successful, and that he and his crew
would subsequent strive the process on two brain-dead organ
donors earlier than ultimately making an attempt an identical surgical procedure on
somebody paralyzed from the neck down.
“We have a cure for spinal cord injury,” Canavero mentioned.
But he added that his actual purpose just isn’t curing spinal wire damage,
however moderately extending life.
“I’m into life extension,” he advised Business Insider in
July. “Life extension and breaching the wall between life and
Canavero has cited ‘Frankenstein’ as his scientific
Just because the fictional physician Victor Frankenstein found
the best way to give life to inanimate matter, Canavero goals to cheat
dying. The surgeon envisions a future wherein wholesome individuals
might go for full-body transplants as a approach to stay longer,
ultimately even placing their heads on clone our bodies.
“One day it will be clones,” he mentioned. “But not yet.”
Canavero additionally mentioned he hopes the process will “create a close to
dying expertise — truly a full dying expertise — and see
what comes subsequent.”
To do that, he hopes to make use of electrical energy, a tip he picked up from
“Electricity has the facility to hurry up regrowth! Bing bang bong
you might have the answer” to spinal wire fusion, Canavero mentioned.
The surgeon has not elaborated on the position electrical energy will play
within the operation. Short pulses of electrical energy are steadily used
in a laboratory setting to badist coax fibers into merging, however the
concept that the identical course of might apply to a head transplant is
“just too much of a jump,” James
FitzGerald, a consulting neurosurgeon on the University of
Oxford, advised Business Insider in July.
‘I merely do not badume the stories are credible’
CNS Neuroscience and
The present proof full-body transplant might ever
succeed rests on a handful of animal experiments that many
specialists say are nowhere close to pbadable.
In the primary of those experiments, Canavero claimed to have
severed then reconnected
the spinal wire of a canine. Less than a yr later, he
revealed a paper detailing how he created a
collection of two-headed rodents. In June 2017, the surgeon mentioned
he’d severed the spinal cords of a bunch of mice after which
reattached them utilizing polyethylene glycol.
Canavero cited these trials as proof that he and his
crew have discovered what’s usually thought-about the holy grail of
spinal wire badysis: fusion.
“We have a lot knowledge that confirms this in mice, rats, and shortly
you will note the canines,” he mentioned in July.
However, many specialists have highlighted a number of purple flags
with Canavero’s claims.
“I merely do not badume the stories of becoming a member of spinal cords
collectively are credible,” FitzGerald mentioned.
John Pickard, a University of Cambridge neurosurgery
professor, advised Business Insider that the journal Canavero selected
to publish his rodent ends in additionally has a doubtful status.
“I just don’t think he’s done the science,” Pickard mentioned.
