NettetN2 - Movement related cortical potentials (MRCPs) have been studied for many years and controlled using brain computer interfaces (BCIs). Furthermore, MRCPs have been proposed as reliable and immediate indicators of cortical reorganizations in motor learning and after stroke. NettetThe proposed method was tested on the attempted hand and arm movements dataset containing EEG signals of 10 participants with spinal cord injury and showed that the filter cutoff frequencies used in the preprocessing had a significant effect on the accuracy.
