What Is Neuralink's Human Trial and How Can You Apply?

Updated

Neuralink's human trial is the PRIME Study (Precise Robotically Implanted Brain-Computer Interface), an early-stage feasibility trial testing the N1 implant and the R1 surgical robot in people with severe motor impairment. You do not apply directly to the trial; you join Neuralink's patient registry, and the team contacts registry members who may match the study's eligibility criteria. Because this is a first-in-human feasibility study, participation means surgery, regular follow-up visits, and a set of risks and unknowns that are still being characterized.

What the PRIME Study is testing

The study evaluates two pieces of hardware together:

  • The N1 implant — a small device placed in the brain that records neural activity and transmits it wirelessly to an external app. The goal is to let a person control a computer cursor or keyboard through thought alone.
  • The R1 robot — a surgical robot designed to place the N1's fine threads into the brain with precision that a human surgeon could not achieve by hand.

The purpose at this stage is feasibility: can the implant and robot be used safely, and does the system let participants control a computer? It is not a trial of a finished consumer product, and it is not designed to cure the underlying condition.

Who is eligible

The study targets people with severe motor impairment, specifically those with:

  • Quadriplegia
  • Paraplegia
  • ALS (amyotrophic lateral sclerosis)
  • Other conditions causing severe motor impairment

Eligibility is not automatic for anyone in these groups. Neuralink reviews registry entries against the study's criteria, which include factors like age, the nature and stability of the condition, and whether a candidate can safely undergo surgery and take part in follow-up. The company has not published a complete public checklist, so the practical answer is: register, and let the screening process determine whether you fit.

What participation involves

If you are selected, participation generally includes:

  1. Screening and consent — medical evaluation and a full explanation of the study, including risks, before you agree to take part.
  2. Surgery — implantation of the N1 using the R1 robot, performed by a surgical team.
  3. Device training and use — learning to use the implant to control a computer, typically through the Neuralink app.
  4. Follow-up visits — scheduled sessions to monitor the implant, your health, and how the system performs over time.

The exact schedule, number of visits, and duration are set by the study protocol and explained during screening.

How to apply

Neuralink does not accept direct trial applications. The path is:

  1. Go to Neuralink's patient registry on the company's website.
  2. Submit your information through the registry form.
  3. Wait to be contacted — Neuralink reaches out to registry members who may be eligible for the PRIME Study or future trials.
  4. If contacted, complete screening and, if you qualify and choose to proceed, enroll.

Registering does not guarantee selection, and being contacted does not guarantee enrollment.

Risks and unknowns

This is an early-stage feasibility trial, which shapes what participants should expect:

  • Surgical risk — brain surgery carries risks including bleeding, infection, and complications from anesthesia or the procedure itself.
  • Device risk — the implant may not work as intended, may stop functioning, or may need to be removed or replaced.
  • Unknown long-term effects — because the technology is new in humans, long-term effects on brain tissue and device durability are not fully known.
  • No guaranteed benefit — the study is testing whether the approach works, not delivering a proven treatment.

Anyone considering the registry should discuss it with their own physicians and weigh the trial's requirements against their situation. The decision is personal, and the study team is required to explain the risks in detail before anyone consents.
