Post-decision processing in primate prefrontal cortex influences subsequent choices on an auditory decision-making task

Decision-making Signals in the Primate Parietal Cortex

From affective value to decision-making in the prefrontal cortex.

Representing the affective value of a reward on a continuous scale may occur separately from making a binary, for example yes vs no, decision about whether to choose the reward. To investigate whether these are separable processes, we used functional magnetic resonance imaging to measure activations produced by pleasant warm, unpleasant cold, and affectively complex combinations of these stimul...

Executive control and decision-making in the prefrontal cortex

action sets thus comprise multiple stimulusaction and (stimulus)-action-outcome associations, which are learned and continuously adjusted online for maximizing rewards. Computational modeling suggest that stimulus-action and (stimulus)-action-outcome associations are learned and adjusted through reinforcement and statistical learning respectively [33 ,34], while abstract action sets emerge thro...

Goal-directed decision making in prefrontal cortex: a computational framework

Research in animal learning and behavioral neuroscience has distinguished between two forms of action control: a habit-based form, which relies on stored actio n values, and a goal-dir ected form, which forecasts and compares action outcomes based on a model of the environment. While habit-based control has been the subject of extensive computational research, the computational principles under...

Neuronal Mechanisms of Decision Making in the Prefrontal Cortex

stimulus space’. Figure 1.1: The double dissociation of action and stimulus based decision making between ACC and OFC. The frequency of shifting away from a rewarded response in an action and stimulus based reversal learning task for controls (CTL), ACC lesion patients (dACC) and OFC lesion patients (OFC). From Camille et al. (2011b). Subjects with OFC lesions show deficits in contingent learni...
