If a person is asked to imitate a zombie, one of the key components to the performance is movement. We do know, however, that Capgras delusion is most often seen in patients diagnosed with paranoid schizophrenia and patients suffering from brain injury or dementia. The delusion is characterized by behavioral issues, and neuroscientists don’t actually have a handle on what causes it. This lack of recognition resembles a creepy psychiatric disorder called Capgras Delusion, defined as “the false belief that the people you know well have been replaced by imposters.” Though a zombie may not actually care that this has happened, the disorder is the closest human condition to come close to their utter lack of recognition. All they see is a human they can eat they will not see a sister, brother, friend, or loved one. 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. Zombies are missing this feeling, so damage to the ventromedial nucleus is a good explanation of the creatures’ need to keep eating.Īnother recognizable zombie issue is just that, recognition. More specifically, it is the ventromedial nucleus of the hypothalamus that controls satiety - the feeling of fullness that tells us it’s time to stop eating. Hunger, thirst, body temperature, and sleep are all part of the package, which means that an insatiable hunger could be linked back to this particular brain structure. This part of the brain is responsible for regulating metabolic processes and other basic functions of the human body. This ravenousness isn’t quite normal, and the hypothalamus could be to blame. All zombies do is eat, and it doesn’t seem to matter if they’ve already consumed half the town - they still want more. It’s a safe bet that what a zombie is feeling is hungry.

But luckily, neurologists know the human brain well enough to guess what the not-so-real zombie brain might look like. Unfortunately (or fortunately, really), scientists don’t have any real zombies to run tests on or interview about their current mental state - all we can do is hypothesize. Knowing that brains are a zombie’s favorite snack might be common knowledge, but what about what’s going on in their brains? What is it that makes them insatiably hungry, resistant to pain, and just cognitively,well, not right? Everyone knows that if the zombie apocalypse ever really hits, we’d have to protect our heads from becoming the next meal for an undead dude. They go together like vampires and blood, or werewolves and the moon. Zombies and brains are inextricably linked.
