Description
Summary:A direct brain interface for control of assistive technologies is being developed based on intracranial detection of movement-related potentials. Subjects for this research are patients who have electrodes implanted for monitoring purposes prior to epilepsy surgery. Triggered averaging is used to create event-related potential (ERP) templates related to specific movements. These templates are then cross-correlated with the electrocorticogram (ECoG) to identify individual ERPs. Results from 7 subjects with varying electrode placements have yielded detection accuracies as high as 92%, 100%, and 89% with false-positive identifications of 2%, 4%, and 2% respectively.
