Zombies and brains are inextricably linked. They go together like vampires and blood, or werewolves and the moon. 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. 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?
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. But luckily, neurologists know the human brain well enough to guess what the not-so-real zombie brain might look like. Spoiler alert: It isn’t pretty.

Insatiable Hunger


Visual Recognition


Movement


Reactive-Impulsive Aggression


Zombies may not be upon us just yet, but when they do come, at least we know why they’re acting the way they are — not that it would help much.
