This study tests if levodopa affects reward- and error-based motor adaptation, finding no significant effects on adaptation or neural responses to reward feedback.

The paper investigates how physical effort modulates neural reinforcement learning signals during decision-making tasks involving reward and effort trade-offs.

The paper identifies neural correlates of reward and sensory error processing during motor learning using EEG, finding the FRN is specific to reward feedback while P300 is modulated by prediction error in both tasks.
