"This study team is by no means the only one looking into this, and much of this technology has been used elsewhere," noted Kalaska. "But this team has clearly shown proof of principle that the concept is workable."
"This is important," he added, "because there are hundreds of thousands of neurological patients that have severe motor difficulties caused by disease and spinal cord accidents. Severely disabled patients. And they have no quality of life, they have no independence. So if you can somehow develop a technology that allows these people to simply think about what they want to do and have a device simply do it for them as a result, you can give them a quality of life that they didn't have before. You can take their intentions, and turn them into reality."
