Will a person’s head living in another body still be that person?. The possibility of human head transplant poses many extremely controversial and ethical issues. Will the person’s personality be intact?. Personality allow us as human being to react differently to situations, It also helps us express what we are thinking or feeling our way.
Personality is the image that defines an individual specific behavior, giving a certain meaning to their presence, and to their actions.

The first known cases of head transplant in mammals happened as early as 1908,
American physiologist and pharmacologist Charles C. Guthrie grafted the head of a small mixed-breed dog onto the neck of a larger one whose own head remained intact.
Similarly, in the 1950s Russian scientist Vladimir P. Demikhov transplanted the upper body of a mixed breed puppy including the forelimbs to the neck of a much larger dog by connecting the pup to the other dog's neck blood vessels. At least one of Demikhov's experiments reportedly survived as long as 29 days after the surgery.

Robert J. White was a professor of neurosurgery at Case Western Reserve
University he led in 1970 a neurosurgeon team in the successfully transplant of a head from one nonhuman primate to another which body had already had its own head removed. According to doctor white when the monkey awakened from anesthesia, it regained full consciousness and complete cranial nerve function, as measured by its wakefulness, aggressiveness, and ability to eat and to follow people moving around the room with its eyes. Such monkeys lived for as long as eight days. Doctor white suggested that with the significant improvements in surgical techniques available today and improve postoperative management, it is now possible to consider adapting the head transplant technique to humans. Transplanting the human brain with all its complexity preserved. Doctor white stated that a surgical protocol for head transplantation in humans would require very little alteration from that used in monkeys, although it would need to be scaled up because of the difference in body size between the two species. He believed that the procedure would be easier to perform in humans than in monkeys, because the blood vessels and other tissues of a human are larger than those of a monkey, and surgeons have much more experience operating on the human anatomy.

Doctor white said that eventually this will revolutionize the way we live, living longer and in the future maybe cheating dead itself. Who might benefit from a head transplant? The first candidates for the procedure will probably be people who have been paralyzed from the neck down because of an accident. For reasons that are still unclear, such individuals often die prematurely of multiple organ failure. Although transferring a paralyzed person's head to another body would not at least at this point in the development of the technology allow them to move or walk again, it could prolong their life. And many hope that in the 21st century, physicians will find a way to heal severed spinal cords, so those who have their heads transplanted onto a new body might someday receive sensory information from and gain motor control over it.
Where will bodies for head transplantation come from? The recipient body would be someone who has been declared brain dead. Such individuals already serve as multiple organ donors, so there should be no strikingly new bioethics considerations for head transplantation.

While White thought of it as a possible precursor to human head transplantation, the scientific community reacted with outrage and these days it’s generally thought of as a pretty appalling experiment that achieved virtually nothing of consequence.
Neuroscientist Steven rose say that the human brain and body are inextricable. The brain is an organ in your body , you’re everything in your body. A brain in isolation is no longer you, it is a person who is conscious it is not the brain who is conscious, it is a person who has a mind the brain doesn’t have a mind. A person is the one who has emotions, the brain doesn’t feel.

Transplanting head X into body Y it actually doesn’t make sense cause the whole historical development of brain X has been mark and relate to a particular individual person, cells are develop in particular sorts of ways, connections are made in particular sorts of ways and is far from clear according to rose that those cells will be able to respond in a way that is meaningful in that new context. Doctor rose said he thinks that
Robert white experiment if it can be call an experiment as oppose to an unsavory manipulation should simply be dump as waste paper, and he doesn’t think that any neuroscientist or surgeon or psychiatrist would take it seriously.
