The paper shows two hippocampal integration dimensions persist across adulthood, relate to memory and dopamine distribution, and decline with age.

The paper investigates how reduced dopamine D1 receptor availability in aging is linked to decreased functional specificity in cortico-striatal circuits and poorer memory performance.

The paper shows that dopamine D1 receptor organization in humans aligns with a unimodal-to-transmodal functional gradient and influences network differentiation and connectivity.

The paper investigates how metabolic demands of the posteromedial default mode network (DMN) are influenced by task-positive networks during attention-demanding tasks.

The paper identifies a bi-phasic pattern of age-related dopamine D1 receptor decline, with distinct functional consequences before and after 40 years of age.

This study examines how neural variability during working memory is regulated by dopamine, functional integration, and decision-making using PET and fMRI data.

This study shows that fMRI deactivations in the default mode network (DMN) during cognitive control do not reflect reduced synaptic metabolism, revealing functional heterogeneity in the DMN.
