Yes, but if you simply connected all the blood vessels and nerve channels that come from the brain to machines, wouldn't it be the same thing? The brain needs oxygenated blood to stay alive, and a machine can easily provide that. What's left that goes into the brain? Just the nerves? There aren't any REQUIRED nerves are there? I mean, usually when a major part of the body gets hurt that feeds nerves to the brain, it's the loss of blood circulation that causes death... not the disconnection of that body part from the brain. See where I'm going with that?
