Neuralink brain chip: What is it and how it is making people to extraordinary things using their mind

Neuralink

Elon Musk’s Neuralink implant is redefining the possibilities of brain-computer interfaces (BCIs). Known simply as “the Link,” this coin-sized device has already given users—from Noland Arbaugh to Audrey Crews and Alex—the ability to control computers and communicate using only their thoughts. While the results are remarkable, the journey has surfaced real-world challenges that underscore the complexity of merging mind and machine.

What is the Neuralink chip?

The Link is a small implant fixed into the skull with ultra-thin electrode threads inserted into the brain’s cortex. These wires detect brain signals—patterns of neural activity—and transmit them wirelessly to an external device. The goal is to enable control over computers, prosthetics, or smartphones purely through thought, bypassing the body’s natural neural pathways.

How Neuralink works
Implantation
A surgical robot embeds the Link into a cavity in the skull and threads as many as 1,024 flexible electrodes into the motor cortex.

Signal detection
The electrodes capture faint electrical impulses generated when the user imagines actions, such as moving a cursor.

Data processing
The chip amplifies and digitizes these signals, translating neural patterns into digital commands instantly.

Wireless transmission
Data is sent via low-power wireless protocols to an external receiver—typically a tablet, smartphone, or computer.

Control of external devices
Interpreting software maps the brain signals to actions, like typing text, moving a cursor, or launching commands in games.

Adaptive learning
The system refines its accuracy over time by learning the user’s unique brain patterns and usage habits.

List of people that received Nuralink chip

Noland Arbaugh
Noland, a former athlete who became quadriplegic in 2016, became Neuralink’s first human recipient in early 2024. He regained the ability to type, play chess, and navigate a laptop—entirely via thought. After some electrode threads retracted weeks later, software updates helped restore functionality.

Alex (pseudonym)
Alex received the implant next. Overcoming Noland’s early hardware setbacks, Alex used the device to create 3D designs, play advanced games, and interact with digital art platforms—demonstrating more stable neural control.

Audrey Crews (patient P9)
Audrey became Neuralink’s first publicly known female recipient in July 2025. Paralyzed for over two decades, she regained the ability to write her name digitally and engage with games for the first time in years, sharing her progress widely online.

RJ
A U.S. military veteran, RJ regained basic smartphone and computer control using only mental commands, highlighting the implant’s potential to restore independence.

Others (P6–P9+)
By mid-2025, at least nine participants in the PRIME clinical trial across the U.S. and UK had undergone successful implantations. Though details remain limited, several anonymous users reported early success in binary commands and digital navigation.

Neuralink’s goal extends beyond rehabilitation. Musk has discussed visions of brain-to-brain communication, memory enhancement, and direct mind-AI interfacing. For now, every surgical case provides valuable data, alongside a reminder: the future of BCIs hinges on incremental progress, deep medical safeguards, and the courage of early adopters.
