The brain-computer interface (BCI) developer is teaming up with researchers to advance two interconnected areas of neuroscience research. They hope to advance AI-driven sensorimotor function and neuroprosthetics.
Precision Neuroscience develops the Layer 7 cortical interface system. The high-density, ultra-thin cortical electrode array enables BCI technology that aims to address paralysis. Using AI models, it translates brain activity into a code that can help inform motor function restoration.
Layer 7 features 1,024 electrodes embedded in a flexible film that conforms to the brain surface. It comes in at one-fifth the thickness of a human hair. This device aims to help users with severe paralysis operate digital devices, like computers and smartphones, using their thoughts.
The New York-based company won FDA clearance for Layer 7 in April 2025. With the clearance, Layer 7 got the green light for commercial use with implantation durations of up to 30 days. The company said it was the first full regulatory clearance granted to a company developing a next-generation wireless BCI. It also partnered with Medtronic this year to further advance BCI technology.
Dr. Peter Warnke and Dr. Charles Greenspon lead the clinical research team at UChicago Medicine Sensorimotor Bionics Group. They bring specialized expertise to the collaboration, as the institution continues to investigate human BCI.
Commentary from Precision Neuroscience officials and researchers
Jayme Strauss, chief clinical officer at Precision Neuroscience, said:
“For people with ALS or brainstem stroke, the loss of movement and speech isn’t just a deficit—it is isolation. We have very few tools today that can meaningfully address the damage caused by these conditions. Our partnership with UChicago Medicine is advancing our understanding of these conditions while helping us turn the neural data we collect into actionable clinical insights. Together, this work is bringing us closer to restoring what’s been lost for this population.”
Dr. Peter Warnke added:
“With Precision’s BCI technology, our team can now capture rich neural data without damaging the brain, giving us new ways to study how it understands and generates movement. This research could help us better understand the planning and execution of physical actions and can ultimately inform assistive technology devices or neurorehabilitation.”
