In Night of the Living Dead, zombies are brought back from the dead by a "mysterious force" that allows their brains to continue functioning. But how exactly does a zombie brain function? Finally, a Harvard psychiatrist has the answers.

Through education Dr. Steven C. Schlozman is an assistant professor of psychiatry at Harvard Medical School and a lecturer at the Harvard School of Education. He is also an avid sci-fi and horror fan - and, apparently, the world's leading authority on the neurobiology of the living dead. He has even drafted a fake medical journal article on the zombie plague, which he calls Ataxic Neurodegenerative Satiety Deficiency Syndrome, or ANSD (the article has five authors: one living, three "deceased" and one "humanoid infected").
