Will a brain transplant ever be possible

Postby bill86 » Tue Nov 23, 2010 10:12 pm

I've also heard about someone sowing a dog head onto another dog body so you have a 2 headed dog is this true?

No to both. As far as I can see.

for the dog, there might be a dog with a dead/useles head, but nothing more because:
Brain transplant is likely to never possible because of the impossibility to map exactly the nervous connection from one brain to another body. So some functions might be more or less re-established, but generally, most of it would get lost.

A personal opinion. Would love to be proven wrong.

I would think that for anything to be deemed possible or not we would have to completely understand how the brain works. At present, we don't fully understand our brains.

Not yet. But I can see in the far future that it can be done.

Sorry to sound gruesome, but wouldn't it be simpler to transplant a head, rather than a brain? You'd 'just' (!!!) need to mesh the spinal column in....(I mean, as far as creating a neuological whole organism is concerned)(mind you, the rest if probably just plumbing!!!)

Aren't there folk in California who have head their heads cryogenically preserved for that very eventuality in the future?

The head will probably save you a bit of work(eyes etc) but the problem is the spine. Since it is both essential and AFAIK it is mapped during our development a direct mapping of spine A to brain B is probably very unlikely.

As for the frozen head, according to someone who is studying cryogenics in nature (some frogs do freeze over) this is a wonderful waste of money. The freezing killed the cells already. Crooks are making money with empty promises.

But what about when docs do surgery at v. low freezing temps (forgotten what it's called - cryo/hypo-arrest or somethign like that)? The person is technically 'dead' because they are so cold, but can be warmed up and revived post op.

I wouldn't say it's common practice, but I definitely saw a programme on it a while back - it's the reason that sometimes we can survive drowning at v. v. low temps.

To be honest, I can't remember why the cells don't burst as the water content freezes - maybe they inject some kind of antifreeze??!

That said, I think the problem with cryogenic preservation is that you don't exactly know what you'll be woken up to - I can think of a lot of dystopian futures where I wouldn't want to be alive, and certainly not as a head, or even as a body in some kind of lab-stasis. Besides, would one want to wake to such an alien world, with no family or friends left in it (unless of course there was a cryo-pack you all signed up to!)

(As an aside, I wonder what happens to your estate? No point divvying it up amongst relatives - you want it kept in a nice swiss bank account for compound interest to make it worth a bob or two when you wake up!)(mind you, probably all goes on the fees of the cryo-crooks!)

They are definitelly not dead! They are not frozen, only cooled! To something like 0 - 4 °C so you slow down the metabolism (crucial e.g. for brain with no oxygen supply), but you do not freeze or elsehow kill the body ;)

Cis or trans? That's what matters.
