Zusammenfassung

Depletion imposes both need and desire to drink, and potentiates the response to need-relevant cues in the environment. The present fMRI study aimed to determine which neural structures selectively increase the incentive value of need:relevant stimuli in a thirst state. Towards this end, participants were scanned twice : either in a thirst or no:thirst state : while viewing pictures of beverages and chairs. As expected, thirst led to a selective increase in self:reported pleasantness and arousal by beverages. Increased responses to beverage as compared to chair stimuli were observed in the cingulate cortex, insular cortex, and the amygdala in the thirst state, which were absent in the no:thirst condition. Enhancing the incentive value of need:relevant cues in a thirst state is a key mechanism for motivating drinking behavior. Overall, distributed regions of the motive circuitry, which are also implicated in salience processing, craving, and interoception, provide a dynamic body:state dependent representation of stimulus value.
