Precision Neuroscience publishes an atlas of human brain and spinal cord recordings from 70 patients

Precision Neuroscience/Layer 7 Cortical Interface

Precision Neuroscience has published an atlas of human central nervous system activity, built from surface recordings made with its Layer 7 implant in 70 patients at twelve academic medical centres. It covers motor, sensory, language, speech and auditory cortex and, for the first time at this resolution, brainstem and spinal cord. The company presents the atlas as part of its work toward an implantable brain-computer interface and says it will grow with each enrolled patient.

• The arrays record from up to 1,024 channels at a 400-micron pitch; the company says this samples more than 600 times more densely than current clinical standards, without naming them.
• The release cites more than 180 hours of synchronised neural and behavioural data and over 100,000 unique anatomical locations.
• The manuscript is posted on bioRxiv, a preprint server; the release does not say it has been peer-reviewed.
• The company says more than 100 patients have now been implanted, so the 70-patient cohort is a snapshot of the dataset, not current enrolment.
• This is a company press release: its 'whole-brain' framing is aspirational, and it reports no clinical outcomes for a permanent implant.
