How Does Neuralink Work?
Neuralink's N1 implant uses flexible electrode threads to read neural signals so people can control computers and other devices with thought.
The implant records electrical spikes from neurons, processes that activity on-device, and sends decoded commands over Bluetooth to an external app.
The N1 implant
The N1 is a fully implantable brain-computer interface with 1,024 electrodes on ultra-thin flexible threads placed in cortical tissue.
The R1 surgical robot
Neuralink's R1 robot helps insert threads with high precision while the neurosurgical team leads the overall procedure.
Bluetooth and the user app
Commands transmit wirelessly via Bluetooth to a phone or computer app. Users calibrate by imagining actions; performance improves with practice.
Patient count
Neuralink reported 21 participants ("Neuralnauts") on January 28, 2026. Neura Pod's patient table counted 27+ publicly identified patients as of June 2026. The implant is not sold to the public; access is through Neuralink's clinical trials and patient registry.
