Abstract:
In this paper a neural model of moral decisions is proposed. It is based on the fact, supported by neuroimaging studies as well as theoretical analysis, that moral behavior is supported by brain circuits engaged more generally in emotional responses and in decision making. The model has two components, the first is composed by artificial counterpart of the orbitofrontal cortex, connected with sensorial cortical sheets and with the ventral striatum, the second by the ventromedial prefrontal cortex, that evaluate representations of values from the orbitofrontal cortex, comparing with negative values, encoded in the amygdala. The model is embedded in a simple environmental context, in which it learns that certain actions, although potentially rewarding, are morally forbidden.
