The paper shows that extracellular dopamine in human striatum encodes both reward and punishment prediction errors through separate pathways during a learning task.

This study measures sub-second dopamine signaling in patients with and without impulse control disorder during risky decision-making, finding increased risky behavior and exaggerated dopamine responses in those with ICD.

The paper quantifies how time perception varies with motor and non-motor symptoms in Parkinson's disease, linking these differences to dopaminergic mechanisms.
