Brain-Computer Interface Systems

What are brain-computer interface systems?

Brain-computer interface (BCI) systems allow people with severe paralysis and speech impairment to control devices and interact with the digital world using only their thoughts. Their brain signals control the external device, restoring communication and independence.

BCIs bypass the body's natural pathways to facilitate direct communication between the brain’s electrical activity and external devices. BCIs can either read brain signals to control the devices, or they can send signals to the brain to stimulate it.

The BCI will analyze the brain signals and translate the information into commands that the device will put into action.

There are two main types of BCI:

• Invasive BCIs: These are connected directly to brain tissue via surgical procedures. Implanted, invasive BCIs are used in medicine for patients with severe paralysis, neuromuscular disorders or injuries.
• Non-invasive BCIs: These are devices that are worn, which have electrical sensors and act as a two-way channel of communication between the brain and a machine. Non-invasive BCIs produce weaker signals as they are not connected directly to brain tissue.

What are the applications of brain-computer interfaces?

Invasive BCIs have many exciting potential applications in healthcare. They can help individuals with neurological conditions regain communication and movement capabilities, they can analyze brain activity related to communication, and they can translate brain signals into commands to control things like prosthetic limbs.

Clinical trials are currently looking at theNeuralink N1 Implant, a type of BCI, and how it can improve the lives of those affected by paralysis and speech impairment.

What is the Neuralink N1 Implant?

The Neuralink N1 Implant is a fully implantable, wireless BCI designed to help individuals with severe paralysis and speech impairment to control external devices and communicate more independently with their thoughts.

Currently under clinical trials, the Neuralink implant marks a significant milestone in BCI technology, with the potential to restore autonomy to people with speech and movement limitations.

How does the Neuralink N1 Implant work?

The implant records brain signals via 1,024 electrodes distributed across ultra-thin threads, each finer than a human hair. The threads are precisely inserted into the brain using the Neuralink R1 Robot.

Once in place, the N1 Implant detects brain signals corresponding to intentions, such as intended movement or speech, and transmits them wirelessly to an external app. The app decodes these signals into digital commands, allowing direct communication between the brain and digital devices, using only thoughts.
