Elon Musk's Neuralink: Brain Implants, Research, and Development

Neuralink was founded in 2016 by Musk and a group of scientists and engineers, and publicly revealed in 2017.^[1][2] Tim Urban's long Wait But Why essay on the company explained its rationale: the brain's output to computers is limited by slow channels such as typing and speech, and a direct, high-bandwidth interface could transform medicine and, in the long term, how humans interact with technology.^[2]

Musk has described the near-term mission as restoring abilities to people with neurological conditions, and the long-term aim as helping humans keep pace with advanced artificial intelligence.^[1][3]

The N1 implant is roughly the size of a coin and sits flush with the skull. It connects to 64 flexible threads, each thinner than a human hair, carrying a total of 1,024 electrodes that record the activity of neurons.^[3][4] The device is sealed, charges wirelessly and transmits data via Bluetooth to a computer or phone, where software decodes the user's intended movements.^[4]

Because the threads are too fine and delicate to place by hand, Neuralink built the R1 surgical robot, which inserts them precisely while avoiding blood vessels.^[3][4] In 2026 the company described moving toward a near-automated procedure as it prepares for much higher volumes.^[5]

In May 2023 the U.S. Food and Drug Administration cleared Neuralink to begin human trials. Its first study, known as PRIME, focuses on people with quadriplegia due to spinal cord injury or ALS.^[4]

On January 28, 2024, surgeons implanted the first device in Noland Arbaugh, a 29-year-old paralyzed from the shoulders down after a 2016 accident at a summer camp.^{[3][6][12][13]} He soon controlled a cursor with his thoughts, played chess and the strategy game Civilization for hours at a time, and described the experience as life-changing.^[3][16] Some electrode threads later retracted, but software refinements restored and even improved his cursor performance.^[6]

Additional participants followed in the United States and later in Canada, the United Kingdom and the United Arab Emirates.^[5][7] Participants — who call themselves "Neuralnauts" — have used the implant to design objects, play games, text family members and, in 2026, steer powered wheelchairs using decoded brain signals.^[7][8] By September 2026 more than 20 people were using Neuralink implants in daily life.^[7]

Neuralink's next major product, Blindsight, is designed to restore vision by stimulating the visual cortex directly, potentially even for people born blind, provided the visual cortex is intact. It received the FDA's Breakthrough Device designation in September 2024, and in 2026 Neuralink was advancing it toward first human trials.^{[4][9][11][14][15]}

The company is also working on restoring speech and on robotic-arm control. In 2026 Neuralink reported plans for high-volume production of the N1 device, and secondary-market trading implied a valuation near $42 billion.^[5][10]

Brain-computer interfaces have been studied for decades, but earlier systems generally required wired connections through the skull and were confined to laboratories. Neuralink's fully implanted, wireless device used at home is a major step toward a practical medical product.^[1][3]

For supporters, Neuralink is one of Musk's most humane ventures: a technology whose first beneficiaries are people who have lost the ability to move or speak, and who are regaining independence through it.^[3][7]
