Robotic arm controlled by thoughts aids paralyzed man

Researchers at UC San Francisco have developed a brain-computer interface that allows a paralyzed man to control a robotic arm using his thoughts. This marks a significant advancement, as previous devices only functioned for a short time without adjustments. The new device can operate for up to seven months without needing external help, thanks to artificial intelligence that adapts to changes in brain activity. This improvement enables more precise movements and reduces the need for constant oversight. Tiny sensors implanted in the man's brain detect his thoughts about specific tasks, like moving his fingers. The AI adjusts for slight shifts in brain activity, enhancing the device's effectiveness for users with paralysis.
