Brain Implant Basics
The core of Neuralink's BCI is a brain implant that records neural activity. This device consists of thin, flexible threads containing numerous electrodes. These threads are inserted into specific brain regions associated with movement control.
The electrodes detect electrical signals from nearby neurons. These signals are then amplified and processed to extract information about intended movements.
Neuralink's approach allows for a high number of recording channels, potentially providing more detailed neural data than traditional BCIs.
The N1 Implant
Neuralink's first-generation implant for human trials is called the N1. This coin-sized device is designed to be placed in the brain's motor cortex.
The N1 contains over 1,000 electrodes spread across 64 threads. Each thread is thinner than a human hair, allowing for precise placement with minimal tissue damage.
The implant wirelessly transmits recorded neural data to external devices for processing. This eliminates the need for wired connections through the skull, reducing infection risk.
Surgical Robot and Procedure
Neuralink developed a custom surgical robot, known as the R1, to perform the precise implantation of electrode threads. The robot uses advanced imaging and micron-scale manipulation to insert threads accurately.
During the procedure, the R1 robot creates a small opening in the skull. It then inserts the electrode threads one by one into predetermined locations in the brain.
The robot's precision aims to avoid blood vessels, potentially reducing surgical risks. The entire process is designed to be minimally invasive and relatively quick.
After implantation, the small incision is closed, leaving only the N1 device under the scalp. The patient can then begin using the BCI system to control external devices through their neural signals.
