Neural Noise- On 21 July 2026, Precision Neuroscience announced that neurosurgical patients without paralysis, temporarily implanted with its Layer 7 subdural microelectrode array during scheduled tumor or epilepsy-monitoring procedures, controlled cursors and played Mario Kart, Pong, and Fruit Ninja, scrolled Instagram, and answered FaceTime calls using thought alone.1
- The Layer 7 Cortical Interface is a thin-film, non-penetrating subdural array with 1,024 microelectrodes, about one-fifth the thickness of a human hair, placed on the cortical surface during the same hospital stay as a scheduled neurosurgery and removed at bedside in under five minutes.1
- Chief Clinical Officer Jayme Strauss said a number of patients had completed comparable sessions, describing this as the first public demonstration of sustained, multi-day thought-based control of everyday consumer computing tasks in non-paralyzed neurosurgical patients; the company’s first chronic, permanent implant in a paralyzed volunteer is targeted for early 2028 via a separate Early Feasibility Study.1
- On 23 July 2026, Precision Neuroscience appointed John Donoghue — the BrainGate pioneer whose Brown University lab produced the first demonstrations of paralyzed patients controlling a cursor, robotic arm, and paralyzed limb via neural signals — as Scientific Advisor, covering device design, signal decoding, and clinical strategy.2
- The company noted Layer 7 has now been implanted in almost 100 patients across academic medical centers, with $180 million raised to date and FDA 510(k) clearance already in hand for the cortical surface array.2
