Oh, to pose a question of anthopology. Or is it pyschology? It's something-ology

I wonder, do you think that people's brains, when they transfer between bodies, that they retain such things as muscle memory? I mean, it might make sense for that to be retained, being a memory and all, but the new body probably doesn't have the same muscular capacity as the old body did. So, what would happen? Would you go to do something that requires muscle memory, like throwing a football, and totally over-or under- compensate for it? Or would you simply have no memory at all, and just have to learn how to throw a football all over again?

This opens up a whole new can of worms: how then do you walk? Surely such a thing is muscle memory, something you learn, like where your center of balance is, when you're like 1. You'd have to re-learn that as well. And talking! What about that? You'd have to re-learn how to talk too, if your brain jumped bodies.

I also wonder about your immune system, would you retain your immunities? I know the brain doesn't control antibodies directly or anything like that, but it does hold the Hypathalumus, which controls body temperature, and relgulation of body temperature is something essential to staying healthy.

Wait, that probably wouldn't be working right, either: the Hypathalmus. How would it know how to regulate your body's temperature correctly? It might produce way to much seritonin, too, it might put you in a coma! Wow I really had overlooked this before! You could boil over! What temperature does your body cease to function, is it 108 or 115 degrees Farenheit? You might hit those very easily if you went from a large body to a smaller one. Inversely, you could freeze to death just the same, if you went from small to large.

Dr. Frankenstein probably never took these things into consideration. I doubt they taught such things at Ingolstadt, though, back then they thought that people were born as either criminals or law-abiding citizens. That's why Inspector Javert pisses me off.

But, I digress.

So, it can then be argued that, if you were to successfully perform a cross-body-transfusion-brain-exchange-thing, that you would:
-1) not be able to talk
-2) not be able to walk
-3) not be able to throw a football
-4) your body temperature will go screwball on you, resulting in:
---a. freezing to death
---b. boiling in your own skin
-5) go into a coma from serotonin overdose or underdose
-6) be chased up Mont Blanc by your creator


Note: this was inspired by watching the movie: Here Comes Mr. Jordan (1941).

Now, debate!
 
Does the new body already have a nervous system?
If so, it would mostly be a function of connecting to the nerves. If we're able to reattach a finger, we should be able to reattach the nerves from a brain. We'd likely need hormones to help, though.

Brain transplants have been done with insects, and a modicum of control is retained (though this is a memory from years ago).

I'd imagine that regrowing nerves to a body would be painful.

I thought nerves, like brain cells, could not be regrown?

BTW I like this new "go to post" feature in quoting.
 
It can be hilariously abused. We don't have the forum-link at the bottom of a page anymore, meaning I have to scroll to the top.

There is more than one type of nerve cell. Hormones should allow us to regrow some, stem cells can help regrow others. But this field is really in its infancy. Even 10 years ago, 'common dogma' was that nerve cells could not regrow at all.

How so?

Just hit the "Go To" button at the forum jump at the bottom of the page, it's default to the forum you're in.

I see.

It also brings up the question, what if the body you enter is damaged, or has a 'different type' of nerve cell (BTW I no longer know what the hell I'm talking about) would you then try to regrow all your nerves?

It's very hard to regrow nerves, they'd have to be done intentionally (on a case by case basis), I think. The hormones and cell-signals to get a nerve cell to grow are mostly unavailable in an adult body (we have some nerves in the nose (for smelling) that continue to grow, but that's it). I think, but am not sure, that we can get some minor growth and branching from muscle nerves, but I wouldn't expect any miracles.

That said, if 'brain transplants' get more viable, we'd look into modifying nerve cells to promote growth/branching/etc. I can't figure out how, right now, but there has to be some way of making them more 'young'.
 
We've learnt how to use our muscles using our brain throughout our lives. In someone else's body, everything would need to be done slightly differently. I expect if it ever did occur, that person would have to relearn how to do everything like walking, talking etc. They would not be able to fully control their body properly.
 
Feedback would solve most of the "base" biological problems such as serotonin, concentrating and moving/speaking slowly would fix center of balance and speech, IMO, but you'd have problems when surprised.
 
Hmm, my guess is that the "calibration" of your the new body would take a few months, but there is only one way to find out...
