Thin-film microelectrode array that conforms to the cortical surface without damaging the brain. Thousands of channels can be delivered anywhere on the brain’s surface using our patented, minimally invasive insertion method.
FEATUREs
A modular system of thin-film microelectrodes designed for minimally invasive and reversible surgery
Advanced brain–computer interfaces require collecting and processing large amounts of neural data, potentially spanning multiple brain regions. Our Layer 7 Cortical Interface provides these capabilities while assuring patient safety.
Flexible electrode arrays
Our novel high-density electrode arrays have 600x the channel density of existing widely available arrays, and conform safely to the cortical surface.
Minimally invasive
Our patented surgical procedure allows us to implant electrode arrays on the brain’s surface with a simple, fast procedure. The surgery is completely reversible.
Read and write
Electrodes can record and stimulate, allowing precise bidirectional communication with the brain.
Modularity
We designed our system to be modular, so that multiple arrays can be combined to cover large regions of the brain.
Neural Decoding
We're developing sophisticated machine learning software to translate neural data into computer code.
Thin Film Technology
Each microelectrode array comprises 1024 electrodes ranging in diameter from 50 to 380 μm and is connected to a customized hardware interface.
Array is 1/5th the width of a human hair.
The slit for insertion is less than 1mm across.
Array has ~600x greater electrode density than standard cortical arrays.
Slit insertion method can deliver more than 50 electrodes per second.
Implantation
Minimally Invasive Surgery
The procedure uses a precise oscillating blade to make a 400-micron-wide incision in the skull—the width of roughly four human hairs. The arrays are inserted through this micro-slit, avoiding invasive surgeries that remove large amounts of the skull.
Our arrays can be safely implanted using a novel, minimally invasive cranial micro-slit technique.
Breaking the Neural Code
When the brain processes information or initiates an action, it generates electrical signals. These signals can be captured and recorded at very high bandwidths by Precision’s thin film technology.
We're developing software and machine learning tools to interpret and act on the data we record, translating between the brain’s neural networks and computers.
With our high-density electrode array and machine learning-based software, we can see how brain signals change when a hand is touched in different locations.
*We have conducted this experiment in pigs by gently touching different locations on a pig’s snout, which, like a human hand, is highly sensitive to touch. We have not yet conducted experiments in humans.
Bidirectional Electrodes
The electrode array is capable of bidirectional function, with electrodes able to record from or stimulate neurons.
