How It Works
Surgical Implantation:
A neurosurgical robot carefully implants a small, coin-sized device into the patient's skull and inserts the flexible threads into targeted areas of the brain.
Signal Detection:
The electrodes detect electrical signals produced by neurons when they fire.
Decoding Brain Activity:
Neuralink's software translates these signals into meaningful patterns, allowing a computer to understand the person's thoughts and intentions.
Controlling Devices:
The decoded signals can directly control external devices such as computers, robotic prosthetics, or wheelchairs.
Potential Applications
Paralysis: Restoring movement and communication abilities for people with paralysis due to conditions like spinal cord injuries or ALS.
Neurological Disorders: Potential to treat conditions such as epilepsy, Parkinson's disease, and chronic pain.
Stephen Hawking: Hawking used a cheek-twitch sensor to select letters on an on-screen keyboard. This worked with a speech synthesizer to create his iconic voice.
Stephen Hawking's system was sophisticated for its time but relied on external detection of physical movement.
Neuralink operates on a completely different principle of monitoring brain activity internally.
Ambition: Neuralink is aiming for a far more integrated and seamless brain-computer interface, whereas Hawking's system was primarily an assistive communication tool.
