Its primary product, the N1 chip, is surgically implanted into the skull by a precision robotic system called R1, enabling direct communication between the human brain and external computers or devices. The company's stated mission is to address neurological conditions such as paralysis, blindness, and severe motor impairments, allowing patients to control digital devices using thought alone. In January 2024, Neuralink implanted its first BCI device in a human patient, with the individual subsequently demonstrating the ability to control a computer cursor through neural signals. Headquartered in Fremont, California, the company operates at the intersection of neuroscience, robotics, and semiconductor engineering, and has attracted significant attention for its long-term ambitions around human-AI symbiosis.
