No metabolism
- Zombies, on the other hand, have no metabolism at all. Even if they could magically summon the energy to chomp on some tasty brains, their stomachs (if they even have stomachs) couldn't provide a chemical pathway for nutrients to convert to energy, leaving the undead rather inanimate and, well, lifeless.

Oct 29, 2010 · Based on the average zombie, we can presume a few things about the virus’ relationship to decomposition.

It’s a safe bet that what a zombie is feeling is hungry. All zombies do is eat, and it doesn’t seem to matter if they’ve already consumed half the town — they still want more. This ravenousness isn’t quite normal, and the hypothalamus could be to blame. This part of the brain is responsible for regulating metabolic processes and other basic functio...
Another recognizable zombie issue is just that, recognition. If a friend or family member is turned into a zombie, it’s a pretty safe bet they won’t recognize or care who you are afterward. All they see is a human they can eat; they will not see a sister, brother, friend, or loved one. This lack of recognition resembles a creepy psychiatric disorde...

The slow, lumbering, and arms aloft walking may have been abandoned for some modern interpretations of zombies (looking at youThe Walking Dead), but classic zombies all moved in a pretty similar way. Motion is a complex thing to study and attribute t...
Certainly the most noticeable thing about a zombie is the fact that they want to kill you. And they aren’t going about it in a rational, calm way. This type of mindless violence was described by neuroscientist and Carnegie Mellon professor Timothy Verstynen as reactive-impulsive aggression. Verstynen, who co-authored Do Zombies Dream of Undead Shee...
When the zombies ruthlessly hunt people, they walk with a specific gait, wide-legged and lumbering, thanks to spinocerebellar ataxia. This movement disorder, caused by damage and atrophy in the...
Oct 30, 2013 · Zombies may have impaired brain function in many ways, but they do have a razor-sharp sense of smell — at least when it comes to sniffing out living human flesh.
Jun 10, 2009 · The most likely explanation is that zombies don’t have a properly functioning ventromedial hypothalamus: the region of the brain that lets you know whether you’ve eaten enough.
