Overriding Self-Interest

Researchers in Zurich suspect that the dorsolateral prefrontal cortex may act as a sort of governor on self-interest, perhaps raising the question of whether morality itself is built-in to the brain. I wonder how long it will be until moral relativists claim a physiological basis to their beliefs. Or will creationists snap it up first as evidence of divine design?

Personally, I'm more interested in a jet-powered laptop.
