History of Neuralink

Neuralink Corporation, an American neurotechnology company, was founded by Elon Musk and a team of seven scientists and engineers in 2016, with its first public report in March 2017. The company is focused on developing implantable brain-computer interfaces (BCIs) and is headquartered in Fremont, California. Since its inception, Neuralink has made several significant advancements. One of the major breakthroughs was the development of a surgical robot designed to implant delicate threads into the brain with micron-level precision. The company has also been testing its prototype in pigs and monkeys, with a notable video demonstration in April 2021 showing a macaque playing the video game Pong hands-free, thanks to two brain implants.

The FDA granted Neuralink a Breakthrough Device designation, which expedites the development and review process for devices that offer significant advantages over existing treatments. This designation has enabled Neuralink to move forward with human trials and further develop its technology.

How Does Neuralink Work?

Neuralink’s technology consists of three main components: The Link, The Threads, and The Robot.

The Link

The Link is a small, coin-sized device implanted into the skull, acting as the primary interface between the brain and external devices. It contains over 1,000 tiny electrodes that connect to the brain’s neurons, allowing it to read and write neural signals. The Link also has a battery, wireless communication capabilities, and advanced signal processing.

The Threads

The Threads are flexible, ultra-thin filaments carefully inserted into the brain tissue. These threads connect the Link to specific areas of the brain, enabling precise targeting of neural signals. The threads are designed to minimize damage to the brain and reduce the risk of inflammation.

The Robot

The Robot is a highly specialized surgical tool designed to implant the Neuralink device safely and accurately. The robot is capable of inserting delicate threads into the brain with micron-level precision, minimizing the risk of damage to blood vessels and neurons.

During the implantation procedure, a small portion of the skull is removed, and the Link is placed in the opening. The Robot then inserts the threads into specific areas of the brain, depending on the intended application. Once the threads are in place, the Link is sealed, and the scalp is closed.
