Dopamine biases sensitivity to personal goals and social influence in self-control over everyday desires

This study shows that dopamine receptor availability affects sensitivity to personal goal conflict and social influence in self-control decisions.

Mesolimbic dopamine D2 receptors and neural representations of subjective value

This study links dopamine D2 receptor availability in the ventral striatum to neural representations of subjective value in humans during decision-making.

Reproducibility of the correlative triad among aging, dopamine D2-like receptor availability, and cognition

This study examines the relationship between age, dopamine D2-like receptor availability, and cognition in healthy adults, finding partial mediation of age effects on digit span by D2R availability.

Differential regional decline in dopamine receptor availability across adulthood: Linear and nonlinear effects of age

The paper examines age-related changes in dopamine receptor availability across different brain regions using PET imaging and finds regionally heterogeneous decline patterns.

Individual differences in dopamine are associated with reward discounting in clinical groups but not in healthy adults

This study investigates the relationship between dopamine function and reward discounting in healthy adults and clinical groups, finding no consistent association in healthy individuals but varying correlations in clinical conditions.
