A new AI-driven brain-computer interface (BCI) has allowed a man with tetraplegia to control a robotic arm with his thoughts for seven months without major recalibration—far longer than previous systems.

Developed by UCSF researchers, the system uses AI to match brain signals to movements, enabling real-time corrections and improved accuracy.

The man successfully completed tasks like opening a cupboard and placing a cup under a drink dispenser.

The AI adapted to brain activity shifts over time, reducing the need for recalibration, Science Alert has reported.

Though complex and costly, this breakthrough highlights the potential for advanced neuroprosthetics.

The study was published in Cell.
