Zombie Neurobiology

The Amygdala and Anterior Cingulate Cortex

Absent a properly functioning frontal lobe, a zombie is driven entirely by base emotions - such as rage - that are housed in the primitive parts of our brain, notably the amygdala. There's precedence for this in nature. A crocodile brain, for instance, is mostly driven by the amygdala. Researchers have confirmed this by introducing lesions into the amygdala of animal specimens: the result is a drop in the attack and retreat response that correlates significantly with the amount of damage that's done to that region of the brain. A crocodile without an amygdala isn't really a crocodile. As such, Schlozman argues, "you can't really be mad at zombies, because that's like being mad at a crocodile," adding that it's the delicate balance between frontal lobe and amygdala "that makes us human."
