Yeah, that is why I asked the question. It looks amazing to me that, if a person is brain dead, even if the brain is autonomic, the body's organs can still be preserved for as long as it can: I assume probably 3 days to one week max.

So if someone is brain dead, it means their body could still function without knowing it? Say if, by absurd, that body can be hydrated and fed, can the rest of the body still be preserved?
