Progress in medical science now enables people with severe paralysis to live for many years. Many of these individuals have great difficulty communicating. Some may even be entirely “locked in” to their bodies: their minds are functioning perfectly, but they cannot move a single muscle to communicate in any way. The capacity for simple communication could greatly improve the quality of their lives.
The Laboratory of Neural Injury and Repair at the Wadsworth Center has solved this problem by developing a new generation of brain-based communication interface (BCI) that can provide communication and control functions for people who have lost muscle control. By recording brain waves from the scalp and then decoding them, the system can allow people to operate a personal computer and software, access the internet, generate speech, operate environmental controls, control robotic assistive devices and more.

Certain patients with late stage amyotrophic lateral sclerosis (ALS), high level spinal cord injury, stroke/aphasia, autism, severe cerebral palsy, or multiple disabilities may be unable to utilize even minimal single-switch systems operated by movement such as eye-blink, or breath. The multichannel EEG-based interface allows them to operate a personal computer and both off the shelf and custom applications thereby extending their ability to communicate and perform tasks autonomously.
State of Development
- In use throughout the world by research institutions
- In clinical trials at Helen Hayes Hospital and the Veterans Administration Hospital in New York.
- Federal Drug Administration (FDA) 510K application pending.
- USPTO patent #5,638,826
- Numerous publications – biography below
Licensing and Collaboration
HRI is seeking commercial partners to create medical and rehabilitative devices based on our BCI platform that could enable speech, use of the internet e.g. e-mailing, gaming, Facebook, tweeting, and devices that allow movement of robotic hands and arms, home automation software systems that turn on/off lights, adjust thermostats and change television channels.
- Medical treatment – speech, mobility i.e. robotic limbs, wheelchair movement
- Clinical neurology, neurosurgery and neuropsychology as well as neuroscience research
- Internet – email, tweeting, Facebook
- Military use – e.g. silent communication with troops
- Can restore communication to severely paralyzed people
- Better quality of life by enabling autonomy
- No muscle control necessary
- Personalized calibration to each individual user’s EEG
