Elon Musk’s brain-implant startup, Neuralink, said it has received approval from an independent review board to begin recruiting patients for its first human trial. The company is seeking people with paralysis to test its experimental device in a six-year study. Neuralink is one of several companies developing a brain-computer interface (BCI) that can collect and analyze brain signals. But its billionaire executive’s bombastic promotion of the company, including promises to develop an all-encompassing brain computer to help humans keep up with artificial intelligence, has attracted skepticism and raised ethical concerns among neuroscientists and other experts.
