The brain-computer interface developer Synchron has laid out plans to build an artificial intelligence model trained on the language of cognition—instead of words or pictures—with programs that are fed readouts of neural activity as recorded by the company’s implants.
Through an ongoing collaboration with Nvidia, Synchron said it aims to take a step forward in its analysis of the output of its brain-reading devices, from supervised machine learning to self-supervised.
“We are building a brain foundation model using generative pre-training techniques that learn directly from neural data—abstracting human cognition at its source—to create features that improve our user’s lives,” Synchron’s founder and CEO, Tom Oxley, said in a statement. “This is possible because of our ability to scale large datasets, by making BCI as common as a stent insertion.”
The former Fierce 15 and Fierce 50 winner’s Stentrode device is able to read neural impulses by snaking an electrode-laden implant up into the brain through the blood vessels, with no operations on the skull. The transcatheter device is similar in form to the stents used to reopen blocked arteries in people with cardiovascular disease.

Synchron’s roadmap to developing cognitive AI—with a model it has dubbed Chiral—starts with a project the company announced earlier this year to employ Nvidia’s Holoscan platform. The goal is to provide real-time AI processing on the device itself, to lower latency and improve user response times.
Then, the two will pursue software that is more aware of objects within its environment, where a better understanding of context may help the device accurately decode the wishes of a potentially paralyzed user, such as their expressions of intent for motor control.
Finally, Chiral will be trained as a general-purpose AI, using the 20 patient-years of brain data that Synchron has collected since the launch of its clinical research program.

“We are witnessing a new computing paradigm, where technology is no longer just responding to people—it’s empowering them in entirely new ways,” said David Niewolny, Nvidia’s senior director of business development. “By combining its breakthrough BCI technology with Nvidia AI and Omniverse, Synchron is helping to deliver new possibilities for individuals with disabilities, enabling greater independence, communication, and connection with the world.”
Late last year, Synchron announced that its Stentrode system had cleared a year-long safety study, involving six participants who had lost the use of their arms, with support from the BRAIN Initiative of the National Institutes of Health. All six showed no serious complications related to the brain or vasculature, while also demonstrating the wireless device could capture motor signals and translate them into mouse cursor movements and clicks.
