This study investigates how dopamine levels affect exploration-exploitation behavior in humans, finding that cognitive capacity and sex moderate L-DOPA effects on decision-making.

The paper re-examines the pharmacological effects of L-DOPA on temporal discounting in a large sample and evaluates proxy measures for dopamine, finding a reliable reduction in discount rate with no credible effects from proxy measures.

This study examines how striatal dopamine levels affect dynamic functional connectivity in Parkinson's disease, finding cohort-specific results that suggest dopamine's role in brain network dynamics.

This study investigates whether dopamine manipulation affects illusory pattern perception in healthy individuals, finding no significant effect of L-DOPA on false alarm rates or other measures.

This study shows that Parkinson's disease patients exert less grip force for low incentives, linking reduced motor effort to putaminal dopamine loss.
