A serious discussion about decapitation

Is this real life?
Would it be possible to cut somethings head off and keep it alive by pumping oxygenated blood through its veins?
 
I don't think so.
 
But isn't it just oxygenated blood that a head needs? Not to mention the fact that without all the arms and legs and such, the 'body' won't need so much to function.
 
Oh you meant keep the head alive...

I am not sure if you could keep it alive that way.
 
Well your brain is what controls all your bodies functions so without it there is nothing to tell your heart to beat.
 
lol I thought he meant the body too.
 
I onestly think it would take more then what Fuddlemiff said to keep a head alive, I dunno what exactly.
 
If it's possible, I want to live that way.
 
I'm sure you could, but you would need to attach all that stuff before you cut the body off, otherwise you would have to do it all in the four minutes you would have before brain damage set in.
 
Yes, perhaps it could be done vein by vein.
 
You would also have to make sure a lot of blood did not get out of the head after you cut it off.
 
First of all, I think you'd have to pump the oxygenated blood into the arteries, not the veins, since they'd be the ones to transport it into the head. You would also have to add carbohydrates, lipids and other stuff like hormones to the blood, too, in order to keep the brain functioning. The problem in this is that as far as I know, science cannot say exactly when the brain needs what in which amounts, so it would be extremely difficult to get the mixture right.

I'm not sure, but I think even if it might be possible to keep the brain alive for a small period of time, its activity is dependent on input (that is, nerval impulses) from the body (at least the senses like eyes and ears) - if depraved of sensorial stimulation, the corresponding parts of the brain will degenerate (like a muscle one doesn't use).
 
So if you wanted to attached a new body, you'd have to do it pretty soon. But then they'd probably need a lot of physiotherapy to get accustomed to their new body anyway, since they'd have to wait a few weeks for all the wounds to heal.
 
Would you not have to make sure they are compatable, there could besome kinda organ rejection type stuff that could happen.
 
^ absolutely.
Moreover, although nerves can regenerate to a certain extent, the central nervous system would have been cut off completely, and that is, IIRC, irreversible.
 
You would need to find some way to make a new one.
 
Yeah, he could borrow the spinal cord technique from the Borg, for example, that worked pretty well.
 
I'm thinking nano/stem cell technology would have to be used.
 
hmm, nano/stem cell technology is the most likely known one to be able to help with that. I know that they had some great achievements in the field of tissue regrowth (skin and heart tissue), but don't know about anything that complex as regrowing the whole cross sectional area of the jugula.
 
Two words: robot body.
