The BrainGate collaboration, lead by Dr. John Donoghue from the Department of Neuroscience at Brown University, recently announced they have began recruiting patients to join in the clinical trials of the second iteration of their neural interface system.
The first round of trials was run by Cyberkinetics, an independent neurotech company founded by Dr. Donoghue, but they have pulled out of this next phase due to funding difficulties. Now, a purely academic team based at the Massachusetts General Hospital, these exciting trials will help guide the next generation of neurotechnological interfaces between human brain activity and direct actions on a computer and, eventually, control of prosthetic devices.
The near-term goal of this research is to develop a technology that can assist patients with degenerative neurological paralysis where their brain is trying to talk to its body, but the body just isn't listening. The BrainGate system trains itself to decode electrical activity in the brain and translate recorded signals into a computer for control of an external device. In effect, BrainGate is a bridge that re-routes neural communication to a device that would be designed to replace lost function.
With previous work, the critical success was converting brain activity into the control of a cursor on a computer screen. Although this seems to be a trivial activity, the understanding of the neuroscience behind the actual relationship between specific brain activity and the mechanical control of our environment remains a vital bit of understanding required for the future of neurotechnology. Now, with the BrainGate2 trials starting soon, opportunities to discover new science will hopefully bring us closer to successful devices for assisting patients with ALS, spinal cord injuries, stroke patients, and many others with empowering technologies to live their lives to the fullest.
