What happens to a person's brain implant when the study that placed it ends?

It depends on what was agreed, and for many early trials too little was. Utah arrays have stayed implanted in some participants for more than eight years, under research protocols whose funding, staff and equipment have their own lifespans, and a working implant may be removed, left in place unused, or kept running only while a lab supports it. Reviews of neural device research ask sponsors to plan before implantation for continued access to a device that helps, for maintenance and for removal, so that the end of a study does not decide alone what happens to a part of someone's body.
