From Neuroeconomy to Neuroethics: Towards a Neuroscience of Individual and Socio-Moral Decisions

Neuroeconomics and neuroethics are subfields of cognitive neuroscience that address the neural correlates of distinct, although strongly intertwined, facets of decision-making. While neuroeconomics investigates the neural mechanisms underlying the maximization of personal economic utility, neuroethics integrates such knowledge with that provided by social neurosciences, in order to address typical questions in ethics and moral philosophy. We review the available research to contrast the hypothesis that both individual economic and socio-moral choices rely on a common brain network receiving domainspecific inputs (Extended Common Currency Schema) and the claim that a specific brain network underpins choices in a socio-moral context (Social-Valutation-Specific Schema). In line with the former model, currently available evidence supports the existence of a single brain network associated with both choice types, regardless of the economic individual vs. socio-moral decisional context.
