Neuralink’s N1 Clinical Trial Progress
Advancing Brain-Computer Interface (BCI) Technology
Neuralink is steadily progressing through its N1 clinical trials as it works to bring its revolutionary brain-computer interface (BCI) technology from the laboratory to clinical application. These efforts—spanning patient recruitment, trial approvals in the U.S., and international expansion—pave the way for transformative treatments for patients suffering from neurological conditions. Here’s an overview of the current status and future direction of Neuralink’s clinical research.
1) Patient Recruitment
Neuralink’s Patient Registry is designed for individuals interested in being evaluated for current or future clinical trials. Targeted primarily at patients who have limited or no use of their hands due to conditions such as spinal cord injuries or amyotrophic lateral sclerosis (ALS), the registry plays a crucial role in both advancing technology and improving patient outcomes.
When participants enroll, Neuralink’s medical and research teams review their medical status to determine eligibility for ongoing studies—such as the PRIME study, which assesses the safety and early efficacy of a fully implantable wireless BCI system. Through this process, enrolled patients may gain the ability to control external devices—like computers and smartphones—using only their thoughts, offering the promise of significantly improved quality of life.
Interested individuals can apply via Neuralink’s official website, and registered patients receive the latest updates on clinical trial progress.

2) Clinical Trial Approvals in January and July 2024
Neuralink has successfully completed its first two human clinical trials, conducted in January and July 2024, which have provided valuable insights into the technology’s potential and areas for improvement.
January 2024 Trial
In the first clinical trial, a patient—Mr. Norland Arvo, who became paralyzed following a diving accident—received an implant of Neuralink’s BCI chip. The device enabled him to control a computer cursor using his thoughts, allowing him to engage in activities such as playing chess. However, a few weeks post-surgery, the trial encountered a setback when the electrode wires began to loosen, which diminished the system’s efficiency. In response, Neuralink refined its algorithms and adjusted its signal translation technology to enhance both data transmission speed and accuracy. This initial trial not only confirmed the technology’s feasibility but also highlighted critical areas for technical improvement.
July 2024 Trial
Building on the lessons learned, the second clinical trial incorporated significant improvements. In this trial, the patient received a newly optimized BCI implant, allowing him to perform more complex tasks such as playing video games and designing 3D objects. To address the earlier issue of electrode loosening, the electrodes were inserted deeper into the brain’s motor cortex, ensuring greater stability and overall enhanced performance of the device.
These trials have been pivotal in validating the safety and early effectiveness of Neuralink’s BCI technology, while also guiding further enhancements. For additional details and coverage on these milestones, please refer to the following sources:
3) Clinical Trial Recruitment in Canada
Expanding its global footprint, Neuralink has secured clinical trial approval from Canadian health authorities and is set to initiate its first human clinical trial in Canada. This trial will focus on patients with paralysis resulting from spinal cord injuries or ALS.
The study is scheduled to be conducted at the Toronto Western Hospital—part of the University Health Network in Toronto. Participants will receive Neuralink’s compact brain chip, enabling them to control external devices using their thoughts without relying on physical movement. By extending clinical research beyond the U.S., Neuralink aims to address previous technical challenges and further validate the efficiency and safety of its BCI system for a broader patient population.
