Does the brain need a heart to live?

No Lifer
Assume someone got decapitated and doctors were able to connect the two main arteries going to the brain to an artificial circulatory system that pumped oxygenated and nutrient-rich blood. Breathing is not necessary as it handled by artificial lungs that perform the CO2-O2 exchange.

Would a person in such a state continue to live or would the brain freak out?
 
Considering the brain controls everything from the neck down, it would probably not like the disconnect.
 
some crazy russians kept a dog head alive in a similar fashion to what you described. Very primitive and didn't last long and might not even have been real depending on who you ask..

I think it's possible, but not with current tech.

 
i think the brain would continue to function, but you would have to connect all of the small arteries and viens in the neck to have a functioning head
 
For a serious response, if you could somehow emulate all of the responses/signals the brain gets from the body you could keep it alive and conscious in a jar.
 
Probably not for long. The other organs and glands of the body, which would no longer be there, probably release chemicals that maintain both physical and mental stability. You've got the blood and the oxygen, but you don't have everything that's supposed to be in the blood.

Supposedly fake. If it were real, they would have zoomed out to show more of the apparatus.

Though it is possible that the device was actually tested and the experiment was actually done. However, the head movements would be different due to the neck muscles not being able to work (no body to leverage with).

Very creepy, though. *shudder*

Fake as hell. When the dog was just blinking, it looked believable for a moment. But when the dog started to lick his nose, that's when you see how BS this is. The muscle that controls the tongue would not move so well with the severed head from neck down.

It's a cheesy hide-the-dog-under-the-table trick and sedate the crap out of it.
 
Yeah the movement does look a little odd, it seems like the flinching wouldn't be possible w/out having the neck muscles attached to the body.
