This study investigates sex differences in reward learning by analyzing task engagement and lapse rates in rats during stimulus- and action-based learning and their reversals.

The paper curates and provides analysis-ready diffusion MRI data for pediatric brain white-matter research, including automated quality control using a trained neural network.

The paper uses brain imaging to investigate how narrative and utility processes contribute to juror decision making by analyzing patterns of brain activation during evidence evaluation.

This paper identifies and validates a neural signature of reward using data from 21 studies, showing high accuracy in distinguishing reward from punishment and generalizability across tasks.

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

The paper shows that different analysis workflows by 70 teams on the same fMRI dataset led to varied results, but meta-analysis found consensus in activated regions.

This paper conducts a systematic review and meta-analysis of dopamine drug effects on reward discounting in healthy rats, finding DAT-modulating drugs decrease discounting while D1/D2 antagonists increase it.

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

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.

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

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.
