After enabling people with paralysis to move a cursor on a computer screen, Neuralink has just taken another important step: for the first time, participants in its clinical trial demonstrated the ability to drive a motorized wheelchair using only their own brain activity connected to the chip implanted in their heads.
The demonstration is still part of experimental research, but it shows how brain-computer interfaces are beginning to move beyond the laboratory setting to address real-world challenges in human mobility. At the heart of this technology is the N1 brain implant developed by Neuralink. Measuring about 23 mm in diameter—roughly the size of a coin—it is implanted directly into the motor cortex, the region of the brain responsible for planning voluntary movements. From there, more than 1,000 electrodes distributed along ultra-thin wires record the electrical signals produced by neurons in real time.
Even when a person has completely lost the ability to move their body, those areas of the brain continue to generate electrical activity every time they imagine performing an action. The implant captures these neural patterns and sends them to an artificial intelligence system trained to interpret the user’s intended movement. Instead of moving muscles, these commands control a virtual cursor displayed on a screen—and it is precisely this cursor that acts as the wheelchair’s steering wheel.
By imagining pushing it forward, the user makes the wheelchair move forward. Mental movements backward cause the wheelchair to move backward; movements to the right and left control turns, while different positions also allow the user to adjust the seat and backrest. The farther the cursor moves from the center, the faster the wheelchair goes. During testing, participants navigated indoor hallways and outdoor areas using a camera mounted on the wheelchair itself.
The image was transmitted in real time to the navigation system, allowing the user to follow the route exactly while controlling all movements solely through brain activity. Another important aspect of the project is safety: rather than maintaining an active command indefinitely, the cursor automatically returns to the center position when the user’s concentration wanes; as a result, the chair gradually slows down until it comes to a complete stop.
This behavior reduces the risk of involuntary movements in the event that attention is interrupted while driving. The demonstration is part of the Prime clinical trial, which began in 2024 to evaluate the safety and performance of Neuralink’s brain-computer interface. According to the latest updates from Elon Musk’s company, several people around the world had received the N1 implant as of June 22. Earlier this year, Neuralink reported 21 participants with implants in four countries, while its separate study, GB Prime, in the United Kingdom, had recruited seven patients as of May 2026.
Despite the promising results, it should be noted that the technology is still in the clinical research phase and has not yet received final approval from regulatory authorities for commercial use. Even so, this breakthrough makes it clear that brain-computer interfaces have evolved far beyond simply controlling computers; for the first time, they are beginning to restore physical autonomy to people who have lost the ability to move.
And if this technology continues to evolve at its current pace, controlling machines solely with the power of thought could move beyond the laboratory and become part of the daily lives of thousands of people.
