Overview
Neuralink develops fully implantable, wireless brain-computer interface (BCI) devices designed to record and stimulate neural activity at unprecedented resolution. The company's first commercial device, the N1 Implant, contains over 1,000 electrodes on 64 flexible threads thinner than a human hair, surgically placed by a custom-built robotic neurosurgical system (the R1 Robot). The device streams neural signals wirelessly to external devices, enabling direct brain-to-computer communication. Neuralink's initial clinical target is people with quadriplegia from ALS, spinal cord injury, or other conditions causing severe paralysis. The PRIME (Precise Robotically Implanted Brain-Computer Interface) Study, which received FDA Breakthrough Device designation in 2023, began human trials in early 2024. The first human patient, Noland Arbaugh, demonstrated the ability to control a computer cursor and play video games using thought alone — with record-breaking neural signal throughput. What differentiates Neuralink is the combination of high-channel-count electrodes, a fully wireless system with transcutaneous inductive charging, and a vertically integrated approach spanning custom chips (N1 ASIC), flexible polymer threads, and robotic surgical delivery. The R1 Robot can insert electrode threads with micron-level precision, enabling consistent implantation while minimizing tissue damage — a capability unmatched by manual surgical approaches.
