And then there's the ShadowRun version of cyberzombies: cyber someone out enough and their soul stops realizing that their body is theirs and tries to leave (aka die) but some mages cast a net over the body to imprison the soul. There's also another implant that has to periodically send messages to the brain reminding them of their life. "This is your mother" and the zombie goes "Oh yeah. I have a mother."
