It is becoming clearer how neurobiological mechanisms generate 'liking'and
'wanting'components of food reward. Mesocorticolimbic mechanisms that enhance …

The striatum is essential for learning which actions lead to reward and for implementing
those actions. Decades of experimental and theoretical work have led to several influential …

Environmental stimuli and objects, including rewards, are often processed sequentially in
the brain. Recent work suggests that the phasic dopamine reward prediction-error response …

Learning the value of stimuli and actions from others—social learning—adaptively
contributes to individual survival and plays a key role in cultural evolution. We review …

Pleasure is mediated by well-developed mesocorticolimbic circuitry and serves adaptive
functions. In affective disorders, anhedonia (lack of pleasure) or dysphoria (negative affect) …

Rewards are crucial objects that induce learning, approach behavior, choices, and
emotions. Whereas emotions are difficult to investigate in animals, the learning function is …

In recent years, an explosion of neuroimaging studies has examined cognitive reappraisal,
an emotion regulation strategy that involves changing the way one thinks about a stimulus in …

When rats come to a decision point, they sometimes pause and look back and forth as if
deliberating over the choice; at other times, they proceed as if they have already made their …

I propose a reconceptualization of key phenomena important in the study of emotion—those
phenomena that reflect functions and circuits related to survival, and that are shared by …

The mesocorticolimbic pathway is canonically known as the" reward pathway." Embedded
within the center of this circuit is the striatum, a massive and complex network hub that …
