The addiction-susceptibility TaqIA/Ankyrin repeat and kinase domain containing 1 kinase (ANKK1) controls reward and metabolism through dopamine receptor type 2 (DR2)-expressing neurons

This study identifies ANKK1's role in striatal DR2-expressing neurons, linking it to reward, metabolism, and behaviors associated with the A1 allele of TaqIA.

Odor imagery but not perception drives risk for food cue reactivity and increased adiposity

The paper investigates how odor imagery, not perception, influences food cue reactivity and adiposity in healthy individuals.

Olfactory decoding is positively associated with ad libitum food intake in sated humans

This study shows that olfactory decoding accuracy in specific brain regions correlates with immediate food intake but not long-term weight change in sated humans.

Fat and carbohydrate interact to potentiate food reward in healthy weight but not in overweight or obesity

The paper replicates findings that healthy weight individuals bid more for high-reward food combinations, but not overweight/obesity individuals, and finds a negative relationship between actual energy density and bid amount mediated by food price.
