Comment on How does death with a mechanical/artificial heart work?

  That would seem extremely unlikely, as a brain that’s been inactive for just a few minutes, if the person is revived, there is heavy brain damage.

    Sounds like you just need more frequent snapshots

  Our mind is dependent on the exact wiring and firing potentials of the neurons. This is what stores everything (skills, memories, autonomic functions etc).

  When the neurons die, this information is rapidly lost. Connections break, and triggering potentials collapse.

  Reversing brain death involves reversing that process. It would almost be easier to digitise the brain and simulate it at that point.

  What might be possible is localised repairs. Strokes can take out small, but critical areas of the brain. Rebuilding a speech center is a lot easier. The brain can distribute a lot of functions, if required. Putting new material in and letting it both learn to use it, and teach it to function is within the realms of medicine. It’s the difference however between a skin graft and rebuilding a limb that’s been through a wood chipper from the bucket of parts.
