This study investigates effort expenditure and brain connectivity in chronic low-back pain patients, finding reduced willingness to pursue high reward tasks and linking this to cortico-striatal connectivity.

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 presents a population-based white matter atlas derived from diffusion MRI fiber tractography, including 216 bundles from 2443 subjects.

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.

The paper investigates white matter microstructure correlates of second-order psychopathology factors using twin data, finding associations with general and specific factors.

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.

The paper introduces a framework for analyzing paired brain networks using persistent homology and sparse learning, demonstrating its application to twin fMRI data to assess heritability significance.
