What work (in whatever medium) gives the most complete account of the biological basis for the zombie phenomenon contained therein?
I’m not familiar with anything that does anything more than handwave about a virus. Nothing to explain the apparent lack of need for (much) nutrition, the ability to continue operating after having suffered massive injuries, and so on.
Best I could come up with as a possible explanation for something like zombie-ism involved nanotech gone awry–it was supposed to repair tissues, but ended up simultaneously keeping the body intact past biological death, while deactivating most of the brain, or something. Why the angry faces and hunger for flesh? Maybe it just left the aggression centers on. (And oh yeah maybe it keeps the “I’m hungry” centers permanently activated fsr, so the zombified brain comes up with an elegant solution to satisfy its two sole desires–to eat and to kill people.) Why not attacking other zombies? Iunno… the nanotech recognizes and cooperates with the nanotech contained in other bodies or something.
How does it take over a person so quickly? Good question. Seems like it would need to expend massive amounts of energy to so thoroughly infest a body that it could keep it intact and running so effectively.
Anyway, that’d be a start. Any works of fiction go this far or further?
