NuroLink's Brain Implant Setback
NuroLink, Elon Musk's startup, faced issues with its brain implant technology after initial promising results. The implant, designed for paralyzed individuals to control devices with their thoughts, experienced mechanical problems shortly after being installed in a participant. The unique design of NuroLink's implant, including 64 flexible threads and a coin-sized processing unit, led to some threads retracting from the brain, reducing data transfer rates essential for cursor control. Despite setbacks, NuroLink aims to improve performance through recording algorithm enhancements and sensitivity to neural signals.
