This study investigates how rapid dopamine changes in the striatum affect temporal learning in humans during interval timing tasks with and without monetary reinforcement.

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.
