Elon Musk announced that a Neuralink patient can now control a computer mouse just by thinking through the company's brain implant technology. This represents the first time one of Neuralink's human test patients has demonstrated using neural signals to directly control an external digital device. The patient implanted with Neuralink's device can move the mouse cursor around the screen just by thinking, according to Musk. Neuralink's goal is to help humans control technologies like computers with their minds.
