Journal ArticleDOI
Changes in brain activity related to eating chocolate: from pleasure to aversion.
TL;DR: The hypothesis that there are two separate motivational systems: one orchestrating approach and another avoidance behaviours is supported, suggesting that the reward value of food is represented here.
Journal ArticleDOI
Dissociation of neural representation of intensity and affective valuation in human gustation.
Dana M. Small,Michael D. Gregory,Y. Erica Mak,Darren R. Gitelman,M.-Marsel Mesulam,Todd B. Parrish +5 more
TL;DR: Findings demonstrate a functional segregation within the human gustatory system and show that amygdala activity may be driven by stimulus intensity irrespective of valence, casting doubt upon the notion that the amygdala responds preferentially to negative stimuli.
Journal ArticleDOI
Relation Between Obesity and Blunted Striatal Response to Food Is Moderated by TaqIA A1 Allele
TL;DR: Cross-sectional and prospective data from two functional magnetic resonance imaging studies support the hypothesis that individuals may overeat to compensate for a hypofunctioning dorsal striatum, particularly those with genetic polymorphisms thought to attenuate dopamine signaling in this region.
Journal ArticleDOI
Relation of reward from food intake and anticipated food intake to obesity: a functional magnetic resonance imaging study
TL;DR: Results suggest that individuals who show greater activation in the gustatory cortex and somatosensory regions in response to anticipation and consumption of food, but who show weakeractivation in the striatum during food intake, may be at risk for overeating and consequent weight gain.
Journal ArticleDOI
Feeding-induced dopamine release in dorsal striatum correlates with meal pleasantness ratings in healthy human volunteers.
TL;DR: The results suggest that feeding is associated with dopamine release in the dorsal, but not the ventral striatum, and that the amount of dopamine released correlates with the degree of experienced pleasure.
