BrainGate

BrainGate is a pioneering system that allows direct communication between the brain and external devices through an implanted microelectrode array. It is designed to restore communication, mobility, and functional independence for people affected by neurological conditions like paralysis. The BrainGate system decodes neural signals from the motor cortex to enable intuitive control of assistive technologies such as computer cursors, robotic arms, and functional electrical stimulation systems.

The key component is a tiny microelectrode array surgically implanted in the motor cortex. This array records neural activity, which is wirelessly transmitted and decoded by advanced algorithms. Through machine learning, BrainGate can interpret intended movements and translate them into commands for controlling external devices. This groundbreaking technology has been extensively tested, with participants achieving impressive feats like point-and-click cursor control, handwriting with typing speeds up to 90 characters per minute, and operating robotic limbs.

In addition to restoring communication and mobility, BrainGate is paving the way for developing closed-loop neuromodulation therapies and advancing our understanding of how the human brain works. As of December 2021, the ongoing BrainGate clinical trial had accumulated over 12,000 participant-days of safety data, demonstrating a favorable risk profile comparable to other implanted neurological devices.
