If a person is his mind so that his brain thus head, then, it's not the head which is being transplanted. But it's the body.
So the title should be changed.--95.10.87.61 (talk) 15:47, 10 June 2015 (UTC)

message: Here is some information which can be added to the article.
Head Transplants and Aging
There are two measures of individual aging, : life span and life expectancy.  Life expectancy is the greatest number of years that any member of a species has been known to survive. The human life span is 120 years. The oldest verified person is 119 years ("World's Oldest Person," 1999). James Fries, professor of medicine at Stanford University School of Medicine, developed the compression of morbidity thesis, which states that the maximum number of years a human is known to live is fixed and finite. In developed countries women live six to eight years longer than men.  Life expectancy is the average number of years people can expect to live (Quadagno, 2017).
A recent development in science has the potential to increase the life expectancy of the human race and potentially even increase the human life span exponentially.  Since 2013, Doctor Sergio Canavero has been publicallypublicly promoting the controversial medical procedure of head transplanting (Kirkey, 2019).  Head transplanting would involve the grafting of a person's head onto the body of another.  The biggest rationale for the operation is much like that of transplanting a human head onto a donor cadaver — which would enable someone who has a degenerative disease, such as the late astrophysicist Stephen Hawking , or has total paralysis to have a healthy functioning body (Scott, 2017).  Once perfected, the only long term limits to this surgery would be the health of the human head.
The procedure has been met with skepticism and moral outrage in the medical community.  The consensus in the scientific community is that a head transplant operation is not possible with current surgical capabilities.  Surgeons also argue that the procedure has not been supported with sufficient peer reviewed research. Canavero, an accomplished neurosurgeon who has published dozens of scientific papers, response is that every scientific and medical marvel was initially met with skepticism and anger – including the first heart transplant in 1967 and the first test-tube baby in 1978 (Wolpe, 2018).  Canavero is attempting to do the procedure in China because of ethical laws prohibit him from performing the procedure in the United States or Europe ("Recent Events," 2019).  Transplants have evolved immensely since the first 1950s successful kidney transplant between identical twin brothers. Transplant surgeons today have transplanted hearts, livers, lungs, hands, forearms, voice boxes, tongues, penises, faces and even a womb (uterine). Scientists are even able to grow beating heart muscle from stem cells.  At the same time, advances in immunosuppression have dramatically reduced the risk of transplant rejection .
The biggest barrier to making a head transplant possible is that severed nerve spinal tissue is not able to heal properly.  This is because scarred nerve tissue does not transmit signals well. This issue could potentially be resolved: some recent research at the University of Pennsylvania has shown that tissue-regenerating mice, can regenerate nerves without scarring. In addition, in 1982, Dr. Dorothy T. Krieger, the chief endocrinologist at Mount Sinai Medical Center in New York City, successfully performed a partial brain transplant in mice.   Recently scientists at Rice University in Houston Texas created a compound called "Texas-PEG", which helps knit severed spinal cords. A recent experiment with the polymer on rats allowed a rat to use its limbs after its spinal cord was severed.  In March 2019, Canavero with Ren Xiaoping, published two peer-reviewed medical journal studies showing that dogs and monkeys were able to walk again after their spinal cords were fully cut during surgery and then those spines were put back together again (Hjelmgarard, 2019; Xiaoping, C-Yoon, & Canavero, 2019).  Repairing 'irreversible' spinal cord damage  (Parry, 2019).   Xiaoping is a US educated orthopedic surgeon, who was part of the team that performed the first had transplant in Louisville Kentucky in 1999 (Kean,  2016).
The possibilities of head transplants in changing the long termlong-term life course for the aging is immense.  The United States and Europe should support such research in their respective countries .
