Precision Neuroscience successfully carried out its first in-human clinical study with its neural implant system, yielding high-resolution images of brain activity. This step forward brings the company closer to its goal of helping paralysis patients interact with digital devices by decoding their neural signals.

The Procedure and Results: The first in-human test of Precision Neuroscience's neural implant system took place in an operating room in West Virginia.
  • The paper-thin electrode array was quickly placed on a conscious patient's brain, providing a high-resolution rendering of the patient's brain activity.
  • The electrode array, called the Layer 7 Cortical Interface, is thinner than a human hair, which allows it to conform to the brain's surface without causing damage.
  • Three patients participated in the study, and each had the system placed on their brain temporarily during neurosurgery to remove tumors.
  • The technology worked as expected, giving hope for further applications in clinical and behavioral contexts.

  • The Future of Precision Neuroscience's Technology: Precision aims to help patients with severe degenerative diseases like ALS regain some communication abilities by decoding their brain signals.
  • Their technology could potentially allow patients to move cursors, type, and access social media using their minds.
  • The company has yet to receive approval from the U.S. Food and Drug Administration (FDA), and the journey to market will require extensive testing and data safety collection.

  • The First Clinical Study: Precision Neuroscience conducted its first clinical study in partnership with West Virginia University's Rockefeller Neuroscience Institute.
  • The partners prepared for the procedures for over a year.
  • The patients had Precision's system on their brains for 15 minutes; two were awake during the procedure to capture their brain activity as they spoke.

  • The Company's Approach and Future Plans: Precision Neuroscience is working on an approach to implant their device without the need for open brain surgery.
  • The company plans to continue testing its technology with two more patients as part of its pilot study.
  • Precision hopes to gain full FDA clearance for its first-generation device by next year.
