In other words, dopamine systems are necessary for 'wanting' incentives, but not for 'liking' them or for learning new 'likes' and 'dislikes'. Incentive salience, we suggest, is a distinct component of motivation and reward. The hedonia hypothesis predicts dopamine systems to be maximally aroused during maximal pleasure, that is, during physical commerce with a hedonic reward. We conclude instead that dopamine may be more important to incentive salience attributions to the neural representations of reward-related stimuli. A research university that focuses on students. We conclude that dopamine systems are not needed either to mediate the hedonic pleasure of reinforcers or to mediate predictive associations involved in hedonic reward learning. Based in New Haven, Connecticut, Yale brings people and ideas together for positive impact around the globe. We review neurochemical, electrophysiological, and other behavioral evidence. Hedonic adaptationthat old hedonic treadmill that were all onis part of us (and it keeps us grounded), but we can still increase our happiness set point by working pleasures, gratifications, and meaningful activities into our lives. We discuss these results in the context of hypotheses and data concerning the role of dopamine in reward. quinine, normal learning of new hedonic stimulus values (a change in palatability based on predictive relations), and normal pharmacological hedonic enhancement of palatability. We found normal hedonic reaction patterns to sucrose vs. In a series of experiments, we applied the 'taste reactivity' measure of affective reactions (gapes, etc.) to assess the capacity of dopamine-depleted rats for: 1) normal affect (hedonic and aversive reactions), 2) modulation of hedonic affect by associative learning (taste aversion conditioning), and 3) hedonic enhancement of affect by non-dopaminergic pharmacological manipulation of palatability (benzodiazepine administration). In a study of the consequences of dopamine loss, rats were depleted of dopamine in the nucleus accumbens and neostriatum by up to 99% using 6-hydroxydopamine. Rather, dopamine systems may mediate the incentive salience of rewards, modulating their motivational value in a manner separable from hedonia and reward learning. Linetsky, MD & Francisco M.What roles do mesolimbic and neostriatal dopamine systems play in reward? Do they mediate the hedonic impact of rewarding stimuli? Do they mediate hedonic reward learning and associative prediction? Our review of the literature, together with results of a new study of residual reward capacity after dopamine depletion, indicates the answer to both questions is 'no'.
