Neuralink Reveals Issues With First Human Brain Implant After Surgery

Neuralink, Elon Musk's brain-computer interface company, encountered mechanical issues with its first human brain implant, resulting in connectivity loss. The implant, which helps a quadriplegic man control a computer cursor, had threads that retracted unexpectedly. Despite the setback, the company enhanced the implant's sensitivity and improved cursor control, surpassing initial performance levels.

The issues did not pose a safety risk, but prompted consideration of removing the implant. Neuralink has informed the FDA and believes it can resolve the problems. The patient, Nolan Arbaugh, demonstrated improved control over computer programs using the implant, highlighting significant life improvements and potential future enhancements for individuals with quadriplegia.
