Overview

Precision Neuroscience represents an alternative approach to intracortical recording, developed by neurosurgeon Benjamin Rapoport, a co-founder and early leader at Neuralink. Founded in 2021, the company raised a $250 million Series D in September 2026 co-led by Pershing Square and the Ackman Oxman Institute, and is advancing a unique cortical surface array methodology.

Layer 7 Technology

The Layer 7 Cortical Interface contains 1,024 electrodes positioned on the brain’s surface. The thin-film substrate is roughly one-fifth the thickness of a human hair, enabling high spatial resolution while remaining minimally invasive. The array rests on the surface of the cortex without penetrating brain tissue.

Surgical Advantages

By eliminating penetrating electrodes, Precision Neuroscience reduces risks of chronic scarring, infection, and glial scar formation that affect deeper intracortical implants. The approach requires only a dural incision and leaves the cortex intact, potentially extending device longevity and reliability.

Regulatory Progress

Layer 7 received FDA 510(k) clearance (decision 30 March 2025, announced 17 April 2025) for recording, monitoring and stimulating on the brain’s surface for temporary use of less than 30 days; it does not cover permanent implantation. More than 100 patients have been implanted, and an October 2026 preprint built a nervous-system atlas from the first 70. BrainGate pioneer John Donoghue joined as Scientific Advisor on 23 July 2026.
