Motor Learning in Parkinson's Disease: Underlying Effective Connectivity and Influential Factors

Participants will practice the Swipe Slide Pattern (SSP) task. On day 1, participants perform two runs of the SSP-task (only one pattern), each lasting approx. 10 min, within an MR scanner. During each run, nine trials of 30s are performed, alternated with rest periods of 14s. In addition, instructions are provided before each trial (i.e. view of the pattern, 4s), as well as an answer option (i.e. participants have circle a random number from zero to nine, 6s). For the following four days (day 2-5), participants will continue practice of the SSP-task at home. During the at-home-sessions, participants will perform nine trials of 12 patterns each, alternated with rest periods of 14s. Instruction are also included. During at home practice, the same pattern as during scans is included, in combination with two new patterns.
