It does not make my argument invalid at all. We are arguing about the anatomy of a creature that has been displayed countless times as a different manifestation. Anything is possible when it comes to speculation about said "undead". Additionally, I would argue that if the virus has the ability to reanimate the corpse, it already has enough power to energize the brain in some form or fashion, without the need for consumption.
