Elon Musk’s brain technology startup Neuralink said Wednesday that an issue cropped up with the company’s first human brain implant weeks after it was inserted into a patient. The company revealed in a blog post that in the weeks following the patient’s surgery in January, a number of the implant’s connective threads retracted from the brain, causing a reduction in the signals that could be captured by the device.
In other videos released by the company, Arbaugh appeared to play the racing video game Mario Kart with the brain chip. The latest update comes less than a week after Neuralink’s cofounder, Dr. Benjamin Rapoport, suggested in a May 3 episode of the Wall Street Journal’s “The Future of Everything” podcast that he left the company due to safety concerns.
