This is a weird post, so bear with me.
When some gets their head cut off, they can remain conscious for about a minute before they die. The reasons for their death are obvious - the head (and brain) cannot survive long without blood and oxygen.
But I was just wondering if it is possible for a decapitated head to be hooked up to a machine that functions as an artificial heart - transfused blood is cleaned by a dialysis machine, aerated, filled with nutrients and then pumped into the head where it keeps the brain alive and then pumped out again to go through the entire process again.
Will the head stay alive?
