    Overview of the study design: (A) Prestudy day: examination and familiarization; (B) study day 1: dose 1 (left) and dose 2 (right); and (C) study day 2: dose 3 and motor tasks. Abbreviations: PA, psychophysical assessment, taken every 30 minutes, starting at time 0 after medication, including systolic and diastolic blood pressure, heart rate, PANAS, and side effects (fatigue, dizziness, nausea); post, posttraining.

    The procedural motor learning task. The left side of the figure shows a patient performing the procedural motor learning task. Patients sat in front of a monitor and were asked to press the key on a special keypad corresponding to a given asterisk on the screen as fast as possible. The right side of the figure shows the schematic setup of the task. Note that the correct button in the presented arrangement is highlighted in gray.

    Results for procedural motor learning (procedural motor learning task). Abbreviation: RT, reaction time. Note that conditions differed significantly in block 2, the primary outcome measure, with larger procedural motor learning in the levodopa condition. Error bars indicate the standard error of the mean. *P<.05.
