- Number of Participants Able to Successfully Control of a Variety of External Devices Using Neural Data Recorded With ECoG [ Time Frame: Up to 29 days of device implantation ]Participants will attempt to control devices such as computer cursors, virtual reality environments and assistive devices such as hand orthoses or surface functional electrical stimulators using their brain activity recorded through ECoG.
- Number of Participants Able to Achieve Direct Brain Control of Assistive Devices Using an Electrocorticography (ECoG)-Based Brain-computer Interface System [ Time Frame: Up to 29 days of device implantation ]Participants will be asked to perform, attempt, or imagine performing motor tasks while their brain activity is recorded in order to observe the changes in neural activity during each task.
