Precision Neuroscience Corporation is developing the Layer 7 Cortical Interface, a revolutionary thin-film brain-computer interface (BCI) that conforms to the brain's surface without damaging tissue. The company was founded in 2020 and has raised over $102 million in funding as of December 2024[1].
The Layer 7 represents a breakthrough in BCI technology by achieving the highest electrode density (4,096 electrodes) on the human brain without requiring open brain surgery[2].
The Layer 7 uses a flexible thin-film electrode array that conforms to the surface of the brain. Key features include:
| Feature | Layer 7 | Traditional Invasive BCI |
|---|---|---|
| Electrode Channels | Up to 4,096 | 100-1,000 |
| Invasiveness | Minimally invasive (keyhole) | Open craniotomy |
| Brain Tissue Damage | None (surface only) | Some (penetrating arrays) |
| Recovery Time | Shorter | Longer |
| Reimbursement | Potential for earlier | Longer pathway |
The Layer 7 enables patients with paralysis to control digital devices through thought alone:
The first human implantation was conducted in June 2023 at the WVU Rockefeller Neuroscience Institute[3]. This study demonstrated the safety and feasibility of the thin-film approach.
In May 2024, Precision Neuroscience achieved a world record by placing 4,096 electrodes on a human brain — the highest electrode count ever achieved[2:1].
The company received FDA clearance for its high-resolution cortical electrode array in April 2025, marking a significant regulatory milestone[4].
In October 2025, Precision Neuroscience achieved another milestone: the first high-bandwidth BCI achieved without open surgery[5].
Precision Neuroscience announced a strategic partnership with Medtronic to integrate Layer 7 with Medtronic's neurosurgical platform, leveraging Medtronic's existing hospital relationships and surgical expertise[6].
Layer 7 occupies a unique position in the BCI landscape:
| Approach | Company | Invasiveness | Channels |
|---|---|---|---|
| Thin-film Surface | Precision Neuroscience | Minimally invasive | 4,096 |
| Stent-based | Synchron | Minimally invasive | 16 |
| Penetrating Array | Neuralink | Invasive | 1,024+ |
| Penetrating Array | Blackrock Neurotech | Invasive | 100-1,000 |
| Non-invasive | Kernel/OpenBCI | None | 8-64 |
Precision Neuroscience has indicated interest in exploring cognitive interface applications, including memory augmentation for Alzheimer's Disease patients.
Future versions may support both recording and stimulation capabilities.
Development of fully wireless versions for improved patient convenience.
