Paradigm: training performance Monitoring Presentation
{"Image DocumentName": "Paradigm: training performance Monitoring Presentation", "Image ImageDescription": "All tasks were trained outside of the scanner to ensure proper performance. During scanning participants were supine and wearing hearing protection. Both patients (using the affected hand) and HC (using the right dominant hand) performed fist clenching around a rubber ball. One movement frequency was paced at 1 Hz via metronome. The other was performed at the participant\u2019s maximal frequency. Performance frequency was counted in four blocks and averaged over time during scanning. Performance amplitude was monitored online by a pressure detector connected to an electro-optical biosignal-recorder (Varioport-b, Becker Meditec, Karlsruhe, Germany). The signals were recorded and stored for further offline analysis using PhysioMeter software. Force was adjusted to about 30% of maximal force by visual training with the pressure device prior to measurement. In a separate task, passive wrist flexion-extension were elicited by a nonmagnetic torque motor at 1 Hz to assess possible differences in representation maps without any voluntary movement or effort contribution. All conditions were randomized with respect to their order. These signals were presented via a video-projection controlled by the presentation software (Neurobehavioral Systems, Albany, USA) and triggered by the scanner. training. Paradigm: performance.
