Broadband communication and custom signal-processing chips power a new brain-recording device that may one day help paralyzed people.
A new wireless brain implant could be an important step toward technology that lets people with mobility problems control a computer or wheelchair with their thoughts.
The implant was developed by a team at Brown University in Providence, Rhode Island. The researchers recently reported in the Journal of Neural Engineering that their fully implantable brain sensor can record the activity of dozens of neurons in freely moving subjects. And they showed that the device continued to work after more than a year in pigs and macaques.
The next goal for the team is to test the device in humans. The promise of brain sensors that help paralyzed people regain some mobility is slowly being realized: last year, two groups reported that quadriplegic volunteers had used brain implants to control robotic arms
