Elon Musk’s brain technology startup, Neuralink, has announced a new feasibility study to assess its groundbreaking brain-computer interface (BCI) technology. The study focuses on the N1 implant, a wireless device that enables individuals with quadriplegia to control external devices using their thoughts. This next phase includes testing the integration of the implant with an experimental assistive robotic arm, a development Neuralink describes as a step toward restoring both digital and physical freedom for patients with paralysis.

The study, named CONVOY, will enroll participants from Neuralink’s ongoing PRIME trial, which evaluates the safety and functionality of its wireless implant and surgical robot. PRIME has already demonstrated the implant’s ability to help patients with quadriplegia interact with devices like laptops and smartphones without physical movement or wires.
Progress in Canada and the United States
In addition to the U.S. trials, Neuralink received approval from Health Canada to begin its first international clinical study, CAN-PRIME. Canadian neurosurgeons will recruit six patients with paralysis to receive the BCI implant, with the ultimate goal of enabling them to control external devices through brain activity. Neuralink’s Canadian trial marks a significant milestone in its quest to expand regulatory approval and broaden access to its technology.
In the U.S., Neuralink has already made notable progress. The company implanted its device in two patients earlier this year. The first patient, Noland Arbaugh, a 30-year-old quadriplegic, has used the implant to perform digital tasks such as browsing the internet, posting on social media, and even playing video games. Neuralink has reported similar success with its second patient, who has been using the technology to explore 3D design and enhance motor control of external devices.
Technology Behind Neuralink’s Implants
Neuralink’s BCI technology employs ultra-fine, flexible threads implanted into brain regions responsible for movement planning. The implant wirelessly transmits brain signals to an app, translating them into commands for external devices like computers or robotic arms. The surgical robot used for implantation is designed for precision, minimizing risk and ensuring optimal placement of the threads.
This innovative approach aims to provide a new level of independence for individuals with paralysis. The N1 implant is cosmetically invisible, offering a seamless integration into patients’ lives without external wires or bulky equipment.
Future Prospects and Expansion
Neuralink plans to expand its trials to include eight additional patients by the end of the year, marking a critical step in validating the technology’s safety and effectiveness on a larger scale. The company is also working to refine its algorithm, improving the sensitivity and performance of the implant for varied use cases.
