The N1 implant consists of 1024 electrodes distributed across 64 threads, composed mostly of polyimide with a thin gold or platinum conductor, which are inserted into the brain through an automated process performed by a surgical robot (R1). Each thread consists of an area of wires that contains electrodes capable of locating electrical signals in the brain, and a sensory area where the wire interacts with an electronic system that allows amplification and acquisition of the brain signal.

The N1 is used as part of a product called "Telepathy". This product allows patients - or users - to perform actions simply by using their thoughts.

Neuralink received FDA approval for human clinical trials with the N1 in May 2023. On January 29, 2024, Musk said (opens in a new window) that Neuralink had successfully implanted a Neuralink device in a human on the day prior, and that the patient (Noland Arbaugh) was recovering:"Initial results show promising neuron spike detection". Arbaugh, a complete quadriplegic, demonstrated telepathy during a live-streaming session by controlling a computer and playing video games just by thinking.

On March 20, 2024, Musk announced (opens in a new window) that the next Neuralink product will be called Blindsight, used to restore a rudimentary form of vision to people who are blind.
