TL;DR: It is shown that extensive training on a free‐operant task reduces the sensitivity of participants’ behavior to a reduction in outcome value, and suggested that cue‐driven activation in a specific region of dorsolateral posterior putamen may contribute to the habitual control of behavior in humans.

TL;DR: This work used event-related functional magnetic resonance imaging to investigate hemodynamic responses to monetary rewards and punishments in three experiments that made use of an oddball paradigm and found that robust and differential activation of the caudate nucleus occurred only when a perception of contingency existed between the button press response and the outcome.

TL;DR: Functional MRI results provide direct evidence for the validity of inequality-averse models of social preferences, and show that the brain’s reward circuitry is sensitive to both advantageous and disadvantageous inequality.

TL;DR: It is demonstrated that the caudate responds to positive and negative feedback during learning in a manner analogous to its processing of extrinsic affective reinforcers and indicate that this region may be a critical moderator of the influence of feedback on learning.

TL;DR: In this paper, the authors show that the neural processes that mediate the influence of experienced disjunctions between these events are unknown, and they show differential responses to probabilities of conjunctive and disjunctive reward deliveries in the ventromedial prefrontal cortex, the dorsomedial striatum, and the inferior frontal gyrus.
