Well, wait no longer.

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."

That balance is maintained by the anterior cingulate cortex, which modulates and dampens the excitability of the amygdala as it talks to the frontal lobe. So, when the amygdala gets all stirred up by fear, anger or lust, the anterior cingulate cortex steps on it a little bit, giving the frontal lobe time to think everything through before it sends signals toward the motor cortex and we act upon those impulses.

A zombie would have a dysfunctional anterior cingulate cortex, rendering it unable to modulate feelings of anger. The result? Hyper-aggression.

Well, considering most zombies just lurch, could you really call that "hyper-aggression"?
