„Believe it or not, the guide to surviving the zombie apocalypse is actually derived from real neuroscience. The charts are largely based on a presentation by UC Berkeley neuroscientist Bradley Voytek, who re-created what the zombie brain would look like based on cognitive problems observed in films like 28 Days Later, Shaun of the Dead and The Return of the Living Dead.

Based on that map of the zombie brain, Voytek and a fellow neuroscientist Timothy Verstynen established that the walking dead suffered from a condition they called Consciousness Deficit Hypoactivity Disorder. CDHD is characterized by “the loss of rational, voluntary and conscious behavior replaced by delusional/impulsive aggression, stimulus-driven attention, the inability to coordinate motor-linguistic behaviors and an insatiable appetite for human flesh.”
