FMRI-neurofeedback in Parkinson's Disease

The participants will be instructed to use cognitive strategies to upregulate (increase) their brain activity in the selected brain region, with the suggestion that motor imagery may be particularly effective, for example, mental imagery of swimming or playing a musical instrument. During the rest blocks, the participants will be instructed to relax. The instructions to start and stop the regulation and rest blocks are visualized on a screen in the scanner, and the brain activity of the putamen will be displayed in real-time using a thermometer bar for visualization.

The participants will be instructed to imagine movements during the active blocks. During the rest blocks, the participants will be instructed to relax. The instructions to start and stop the regulation and rest blocks are visualized on a screen in the scanner. No feedback is provided regarding brain activity.
