2 . Nowadays medical technology seems to be advanced enough for doctors to perform brain transplants (移植). Though this procedure (程序) has only been successfully performed on animals so far, doctors are still hoping to perform this procedure on humans. However, in my opinion, brain transplants should not be performed at all, especially not on humans because of the large number of problems and side effects that could come along with. Hopefully these dangerous side effects will convince doctors not to perform this procedure on humans.
Despite many benefits technology brings. I do not think this medical technology of brain transplants will help. We were all born with one brain and through childhood to adults our mind developed into who we are, so if with a different brain we would no longer be unique. A person with a different brain would seem to be a total stranger and in many ways they would be. No one should steal our identity from us, even if we are seriously injured, and change it to a completely new one. Also for the people who have died with healthy brains, that was their identity and it should not be given to anyone else.
Another problem with brain transplants is how doctors can choose what are “healthy” or “normal” brains. An elderly person who has died would have an aged brain that would not be as efficient as younger person’s brain. Then would doctors have to find healthy brains of the same age as the person who needs it? This could also bring up other factors such as intelligence, sex, or physical problems that a person might have had before death. Also another problem might be how long a brain can be kept “alive” after death and how it can be kept “alive” without damage.
Overall. my feelings about this operation are that it should not be done on humans until doctors have overcome all the problems and challenges that stand in their way of making human brain transplants successful.
