100,000 ELECTRODES. 70 PATIENTS. THE HUMAN BRAIN, MAPPED.

Precision Neuroscience announced a manuscript describing a growing atlas of the human central nervous system built from high-resolution surface recordings in 70 patients across twelve academic medical centres. The atlas already comprises more than 100,000 electrode deployments spanning motor and somatosensory cortex, language and speech regions and auditory cortex, and for the first time in such a dataset, brainstem and spinal cord structures.

The data were collected with Precision's Layer 7 Cortical Interface, a thin-film array recording up to 1,024 channels, and include more than 180 hours of synchronised neural and behavioural data from 87,342 individual microelectrodes across more than 100,000 anatomic locations. Precision is developing the implantable interface to restore movement, speech and communication for people with paralysis from spinal cord injury and stroke and with ALS, and says total patients implanted has since passed 100.
