If we could pull off a brain transplant in humans, should we?

are you talking about human to human transplants or human to machine transplants?  an automaton w/ a human brain could, in theory, keep that human alive forever...disrupting the natural balance.  Human to human could be a chance to realy discover how the brain thinks.  We (inside a new body) will be able to see the world from a new perspective (literaly).

The world is already overpopulated and there are too many unwanted or orphaned children. Why would we need to clone a person except to use them as non-humans such as organ producers for organ donation or as slaves, etc. No matter which way you look at it, it is the arrogance of man who is messing with something he has not thought through. The consequences of this capability will be nothing but negative.

A great and difficult question.  One has to determine the greater good for use of limited resources, and unfortunately some will be disappointed.  I was on a organ transplant committee for several years, we would review the patient (age, overall medical condition,family state, social factors, ect) and make a decision as who would have the greatest likely hood of not only surviving the procedure, but thriving with this precious gift.  It is a very difficult process, and a real strain on those personnel required to make those decisions.

Nope, all human beings eventully die.  Theres something in our dna that is being chipped/ shortened as the years go by.  It is our death clock.  No one has found a way to stop that.  If stopped, we will become immortals.  Brain information cannot be downloaded and transferred if not we did all become einsteins by now.  We can only monitor brain activity.\n\n\nBut if I could do the following, why not?

far enough to cure cancer. We should also be able to clone our own organs so that if we ever needed a new heart or lung or whatever, we won't have to wait on a list for a year till someone died in order to get it. \nIf we were able to grow a heart on a dish, then we wouldn't have to wait for someone to die.. and we wouldn't have to worry about rejection because it's our own organ.

Others have wondered whether or not downloading the contents of one's brain into an ultra-high-capacity chip would allow for the continuation of the consciousness. Arthur C. Clarke seems to think so. I'm not so sure, but it is an interesting Q.

NO !!\n\nFirstly, because this essentially puts a price on human life and dignity. Life can be given, it should not be sold.\n\nSecond, because it's usually a short term decision, that can be dearly regretted if you live long enough. You will of course sell only organs you can live without, a kidney or an eye... but what if, later in life, your remaining one fails, and you don't have the money to replace it? You're in the doo doo, possibly dead if it was a kidney.

That is the why human cloning is banned.Because it is more unbenefiatiable.The main thing why this is if this is possible, then a criminal would be clonned in many and you can imagine what the situation would be  if a most criminal person is clonned many.there are many bad thigs than good things about human cloning.But cloning of some parts of human organ or themselves should be done because this would help patients to get new fresh organ.

I would guess that it would be in the field of biochemistry. Perhaps cloning will be the next big thing, where we may be able to growth individual organs for transplants.

Of course NOT. Some answerers above answered "we can do whatever we want to ourselves" but that's WRONG. You can take drug if you want? No you cannot. There is such a thing called SOCIETAL IMPACT. In economics we call it Negative Externality. Some answerers above gave a good answer by saying that allowing people to sell their organ will lead to more crime, whether it's people "robbing" someone's organ, or corporate crime whereby companies exert their influence to manipulate the organ transplant process to maximize their monetary profits.\n\nI hope stem cell research can take off soon -- THAT is the hope in the medical community.

Yes, DNA manipulation in post-natal humans, Has Already Been Done, With Some Success, Consider BMT (Bone Marrow Transplant).

A head on ice would be able to survive for a while, especially if prior to separation induced hypothermia is used to trigger the mammalian diving reflex, and drugs which limit brain damage from anoxia are used.  This may give as much as 30-40 minutes to work with a severed head.  If the dead body is in good shape otherwise, such as a recent death from acute head trauma, and is similarly cooled rapidly to prevent tissue breakdown, you could possibly reattach most major components in that time.  Regrowing the severed spinal cord would be the tricky part, but there is a lot of research going on that suggests it may be possible, especially if correct treatment of the severed spinal cord is taken immediately.  Stem cell grafts or at least application of specific growth factors will probably be needed to complete the connection.  \n\nWith arteries, muscles, skin, and peripheral nerve connections restored, the person could be kept on a heart-lung machine until the spinal cord is repaired to maintain steady breathing and heartbeat. \n\nSo, in short, it's plausible with near-future medical technology, but it's probably risky enough to not be worth attempting yet.  Within 10-15 years, it could be done.  \n\nThe real question would be whether or not the newly connected head could correctly control the body it's attached to.  There are some general levels of organization to the distribution of nerve fibers in the spinal cord, but the I/O pattern in the cervical spinal cord of the grafted head wouldn't be an exact match for the spinal cord in the body.  If the signals are mismatched, and they probably will be, the results could be anything from loss of muscle coordination and control to chronic severe neurological pain.  Whether or not the plasticity of regrowth would allow this to correct itself is unknown.  \n\nIt might end up being easier to graft the head plus spinal cord into the donor body, since the spinal cord to peripheral nervous system connections, plus the cranial nerve to body connections, such as the vagus nerve, are much simpler than the spinal cord.   If bloodflow could be restored within the 30-40 minutes working time this would give surgeons time to finish the spinal graft.  Recovery would still be very extreme, since the spine would have to be completely opened up, and successful recovery of such an invasive procedure is currently beyond our medical capabilities, but there is a lot fo work with artificial spinal disks, bone grafts, and other systems for repairing damaged vertabrae.  \n\nI certainly wouldn't volunteer to be the first patient, but it's plausble that one day it could be done successfully.

no. as soon as the brain is cut off from the body. the body would not walk.

Part of the problem is that we can't fix a severed spinal cord -- and we'd have to sever the spinal cord to transplant just the brain.\n\nSuppose, then, that we transplanted the whole central nervous system?  We'd still have the problem of attaching nerves, and unfortunately they don't regenerate to the extent needed by such a large injury.\n\nWe're not even close to doing such a transplant.  Sorry.

We use all of our brains.  It is a myth that we do not.

No, what if that person's organs die before they are removed? What if the organ's are not compatible? then the suicide would be useless. \n\nDepending on what is needed, sometimes a person can donate while they remain alive.\n\nDonating is a great virtue, but all within it's own time, suicide affects many people and may even affect the person waiting on a transplant
