N1 Implant

The N1 Implant is Neuralink's coin-sized brain-computer interface, which is a device that reads the electrical activity of brain cells and turns it into commands a computer can use. It is flush with the skull, about the size of a United States quarter, and its first skill is called Telepathy: controlling a cursor, a keyboard, or a game by thought alone. The first one went to Noland Arbaugh, a paralyzed 29-year-old, in January 2024, and within weeks he was moving a laptop cursor with nothing but the intent to move it.

What is the N1 Implant?

The N1 Implant is a fully internal brain-computer interface (BCI), which means the whole device is inside the body and reads brain signals without any wires breaking the skin. Neuralink calls it "The Link." A robot inserts its threads into the motor cortex, the strip of brain that plans movement. It charges through the skin from an external pad, so there is no plug and no wire. Its job is to turn the intention to move into a digital action on a screen.

Why the N1 Implant Exists

Neuralink, which Elon founded in 2016 with a team of neuroscientists and engineers, sees the N1 first as a way to give people with serious medical needs their independence back. The near-term target is paralysis. The longer-term idea is much bigger: Elon argues that humans need a fast, high-capacity link to machines so people are not left behind as artificial intelligence keeps advancing.

How it Works

The R1 surgical robot places 64 ultra-flexible polymer threads into brain tissue, each one thinner than a human hair and carrying 16 electrodes, for 1,024 channels in total. The N1 chip inside then processes those signals and sends them wirelessly to an app on a nearby device. The way progress gets measured is bits per second (BPS), which captures how much accurate cursor movement a person can produce each second.

The benchmark is an able-bodied engineer using a normal mouse, at roughly 10 BPS. On October 1, 2026 Neuralink reported a record of 11.32 BPS, with the median participant at about 10.

Neuralink also showed it can improve an implant through software. Weeks after the first surgery, about 85% of the threads pulled back from the brain tissue and cut the number of working channels, The Wall Street Journal reported in May 2024. Rather than open the skull again, Neuralink rewrote the software and recalibrated, and it won the performance back that way. The first participant's speed then nearly doubled from his record-setting first session to his best result.

The Economics of the N1 Implant

The N1 is an investigational device in clinical trials, so it carries no price yet. A $650 million Series E round in June 2025, backed by ARK Invest, Founders Fund, Sequoia, Thrive, Lightspeed, and others, pays for scaling up implants and adding new uses. To reach millions of people, Neuralink needs more participants, more uses, more channels per implant, and a manufacturing cost that keeps falling.

Current Status of N1 Implant

The clearest signal is enrollment. Neuralink calls its trial participants "Neuralnauts," and its January 28, 2026 update reported 21 enrolled worldwide. Neura Pod counts 27+ people with the implant as of October 2026.

Three people were implanted in the first year, and 13 in the second half of 2025 alone. Typing speeds now reach up to 40 words per minute by mapping individual fingers to letters. One participant, a medical student, has used the device up to 17 hours a day to keep up with his studies.

What Comes Next

Neuralink is stretching the N1 beyond movement control. The FDA has granted Breakthrough Device Designations to two new programs: Blindsight, which aims to restore sight by stimulating the visual cortex, in September 2024, and speech restoration in May 2025, which became the VOICE Study that October. In September 2026 Neuralink confirmed that a VOICE participant's implant carries 3,000 channels, about 3 times the N1's 1,024, and it has said later devices will carry more than 10,000.

The Bottom Line

The N1 Implant lets people with paralysis run a computer by thought alone, and some participants now match or beat the speed of an able-bodied person using a mouse. The trials now running in 4 countries are the path from a medical device to the on-ramp for the human-AI partnership Elon describes.
