[FONT="]Regardless of ethical issues, problem is its impossible at this time. Having some animal experiments "survive" for couple of days is eons from something that could actually be considered success. [/FONT]
[FONT="]The article says that they were indeed capable of letting the monkey live infinitely but considered that an “ethical problem” and killed it. Besides the first human heart transplantations weren’t very successful in this regards either.
1. We have no means of successfully reconnection the spinal column. [/FONT]
[FONT="]No never claimed that, you will still be [/FONT]
quadriplegic[FONT="] but at least you have the
choice between that and death/endless chronic pain.[/FONT]
[FONT="]
Organ rejection? I don't even want to imagine it. [/FONT]
[FONT="]2. Well keep in mind that you don’t have any spinal connection to your lower body half, so for better or worse it is kind of an organic lung/heart/dialysis machine combination.
3. Medicine can keep some organs stored for hours and days for transplantation. Brain has 10 minutes without oxygen before real death. Body to which the transplantation is done would also cause a huge time pressure, it can't be stored in any way, you would have to find way to keep the body alive without the brain.[/FONT]
[FONT="]Cooling it down should solve that problem, as mentioned in the article. The more experience they have the better things will become compare this to heart transplantation.[/FONT]
[FONT="]And they succeed with the monkeys.
4. How would you possibly find a donor? Death by accident has the body and organs damage and failure, as well as death by natural causes. [/FONT]
[FONT="]Indeed the worst problem. You have to find someone brain-dead, by head injury or brain tumor and so forth.[/FONT] Here POD leading to a broader donor basis would be useful (probably something like organ donor by default, non organ donor by choice). The positive side effect would be finding better matches for donors and receiving. Still I will probably remain a rather fringe method for a long time.[FONT="]
Brain transplants are for the time being, and at least for next several decades only a thing of grisly fiction.[/FONT][FONT="]
Indeed that why i never referred to brain transplantation but to head transplantation which already happened quite some time ago (in the 1970s). The grisly part is your personal opinion I would like to have the choice at least, though I am not sure how I would decide (not that it is relevant to the chal[/FONT]lenge)
