Dissociating the Role of the Orbitofrontal Cortex and the Striatum in the Computation of Goal Values and Prediction Errors

摘要: To make sound economic decisions, the brain needs to compute several different value-related signals. These include goal values that measure predicted reward results from outcome generated by each of actions under consideration, decision net value taking actions, and prediction errors deviations individuals' previous expectations. We used functional magnetic resonance imaging a novel decision-making paradigm dissociate neural basis these three computations. Our show they are supported substrates: correlated with activity in medial orbitofrontal cortex, central ventral striatum.
