This study investigates how learning affects brain network interactions and metabolic demands, finding that resting-state and task-specific changes in functional connectivity and glucose metabolism are complementary for skill acquisition.

The paper introduces a novel fPET approach to assess dopamine synthesis during reward and punishment processing, revealing sex-specific differences in dopamine response to monetary gains and losses.

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.
