A Neural Network for Moral Decision Making

Some of the most fundamental psychological questions concerning human relations center on morality and altruism. Reinvigorated by the advent of modern technologies such as magnetic resonance imaging (MRI), these questions have been extended to humans, which has resulted in a recent flurry of empirical studies examining the psychological and neural architecture of moral cognition. The depth of this subject is remarkable, and there is insufficient room here to touch on all facets. As a result, this review will cover two questions central to human moral behavior: How do we arrive at our moral judgments? And what is the neural circuitry that underpins these moral judgments?
