Introduction • A brain transplant or whole-body transplant is a hypothetical operation in which the brain of one organism is transplanted into the body of another • Theoretically, a person with advanced organ failure could be given a new and functional body while keeping their own personality and memories.
Historically, brain transplants have not been feasible and were widely regarded as impossible. • Today, given progress in organ transplant and human cloning research, many scientists hold that brain transplants are theoretically possible and likely to be feasible in the future.
Challenges • One of the most significant barriers to the procedure is the inability of nerve tissue to heal properly (scarring) • There is also a potential problem of the new interface at the spinal cord, in that even if all the nerves are connected successfully, they may still be connected wrongly • For example, a nerve that used to control the right index finger's muscle group might be connected to a different finger's muscle group, or another body part entirely. Needs many years of rehabilitation.
Alternatively a brain–computer interface can be used connecting the subject to his own body • The brain is an immunologically privileged organ, so rejection would not be a problem
Partial brain transplant • An arguably more reasonable scenario is a partial brain transplant involving only enough tissue to provide key memories and a sense of continuity of identity • In 1982 Dr. Dorothy T. Krieger, chief of endocrinology at Mount Sinai Medical Center in New York City, achieved notable success with a partial brain transplant in mice. A partial brain transplant could accomplish essentially the same goal — movement of a person's "identity" from one body to another— and thus qualify as a whole-body transplant no less than a full brain transplant
