First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study tested a new brain implant for people with locked-in syndrome, who are awake but cannot move or speak. The implant records brain signals from the surface of the brain and sends them wirelessly to a computer, allowing the person to control a communication device. Six participants tried the system at home to see if they could reliably use it to spell sentences.
