Study Methodology (IMAGE) Society for Neuroscience Caption Patients implanted with electrocorticography arrays completed a 3D center-out reaching task. Electrode locations were based upon the clinical requirements of each patient and were localized to an atlas brain for display (A). B. Patients were seated in the semi-recumbent position and completed reaching movements from the center to the corners of a 50cm physical cube based upon cues from LED lights located at each target while hand positions and ECoG signals were simultaneously recorded. Each patient was implanted with electrodes in a single cortical hemisphere and performed the task with the arm contralateral (C) and ipsilateral (D) to the electrode array in separate recording sessions.
