Precision Neuroscience Surface Film

Precision’s surface film shows the core trade off in BCI design, more signal than fully noninvasive headsets, with less tissue disruption than needles pushed into cortex. Its Layer 7 array is built to lie on the brain rather than enter it, using 1,024 electrodes and a small skull opening, which makes it a middle path between Neuralink’s penetrating threads and Synchron’s blood vessel approach.

• Precision was started in 2021 by Ben Rapoport, a Neuralink co founder, and the company says three of its first four team members had worked together at Neuralink. That matters because it suggests Precision is not rejecting high bandwidth BCI goals, it is changing the implantation method to improve surgical practicality.

• Compared with Neuralink, the main difference is where electrodes sit. Neuralink places flexible threads into brain tissue using a robot, aiming for very high channel counts. Precision keeps electrodes on the surface, which should reduce direct tissue injury but can give up some intimacy with neurons and therefore some signal fidelity.

• Compared with Synchron, Precision accepts a more involved cranial procedure in exchange for higher resolution potential. Synchron delivers a 16 electrode array through the jugular vein into a vessel near motor cortex, avoiding open brain surgery, while Precision places a much denser film directly on cortex through a skull opening.

The market is likely to split by use case. Surface arrays like Precision’s are well positioned if hospitals want a device that can capture richer signals than vascular or headset systems, without taking on the full complexity of deep penetrating implants. That could make cortical surface BCIs the practical bridge from research implants to broader clinical adoption.
