To provide a link between different parts of the brain and computer systems that can help restore visual, auditory, motor, and cognitive functions. Elective Implants Max4e Photo/Īt this early stage, Neuralink is pitching its implant as a next-generation medical device. So a fully sealed implant, such as the type Neuralink promises, would already be a big advancement. Older BCI devices, such as those made by BrainGate, require a port that connects the brain to the outside world. Power is provided to the link device wirelessly without any break in the skin required. In the case of the Neuralink prototype, it consists of incredibly fine electrodes referred to as “neural threads” that are installed by a robotic system, along with a connected Link device. BCIs are distinct from devices that, for example, read the signals from your muscles or are connected to nerves outside of your brain, but those technologies are obviously related to BCIs. The name “brain-computer interface” already tells you most of what you need to know, but in essence, it’s a direct path of communication between the neurons of your brain and a computer system.īCIs have been around for a long time and have been successfully used to allow, for example, paralyzed people to control robotic arms with just a thought. What Is a BCI, or Brain-Computer Interface?
