It aligns more with brain dead. No signals in the brain for life with the motor functions still moveable. The body stays as the consciousness is take from the brain in every cell. The meat you basically posses would be grey not pink and not allow a electrical charge. The crystal is a mirror image of what the charge would be. More LIGHT than electricity.

Think of it as crystals that take your consciousness and places it in a game like Tron. Most people would think Sword Art Online or Code Leioko, but it would technically be inserted into a game or a computer function.
