Elon Musk recently announced that Neuralink, his company aiming to revolutionize brain-computer interfaces (BCIs), has successfully implanted a brain chip in a human for the first time. The implantation of the device, called “the Link,” represents a leap forward in the realm of BCIs, which record and decode brain activity, that may allow for new innovations in health care, communication, and cognitive abilities.

Though limited information on the technology is available and Neuralink’s claims have not been independently verified, here’s a look at the Link, its functionality, and the potential implications of this groundbreaking innovation.
