Precision Neuro: Restoring Freedom Through Brain-Computer Interfaces

The Next Generation of Neural Engineering

Published on


2 min

Alumni Ventures portfolio company Precision Neuro is developing a brain-computer interface (BCI) installed via a patented minimally invasive insertion procedure. Precision’s BCI employs a thin film microelectrode array that conforms to the brain’s cortex without harming the surrounding tissue. This allows thousands of channels to be delivered anywhere on the brain’s surface.

Precision Neuro’s Brain-Computer Interface

Precision Neuro’s Layer 7 Cortical Interface System is engineered to map a large area of the brain’s surface at resolutions hundreds of times more detailed than typical arrays used in neurosurgical procedures. Learn more about the company’s mission to restore meaningful function to millions of people suffering from neurological illnesses and disorders.

A New Kind of Brain-Computer Interface

In 2019 alone, there were nearly 10 million deaths and 349 million disability-adjusted life years due to neurological disorders like Parkinson’s, epilepsy, and multiple sclerosis. Because of their severity and lack of treatment options, neurological conditions can be hard to diagnose and harder to effectively treat.

Legacy BCI technology typically relies on penetrating electrode arrays to function. In other words, the installation of the electrode itself causes brain tissue damage. While reversal of the procedure is possible, it is more invasive and subject to a higher risk of complications due to the invasive approach.

Precision’s BCI takes a different approach. Rather than physically penetrating the patient’s brain, Precision’s BCI is instead a smooth, flexible sensor array thinner than a strip of tape that is carefully positioned on top of the patient’s brain, between the brain tissue and the skull. Dubbed the Layer 7 Cortical Interface, the array not only allows for a less invasive insertion for patients but is capable of capturing vastly more amounts of data over a larger proportion of the cortex than other interfaces, while also maintaining the capability to both read and stimulate regions of the brain.
