Nature Biomedical Engineering paper reports Precision's high-density thin-film arrays decoding and stimulating human cortex

Precision Neuroscience/Layer 7 Cortical Interface

A Nature Biomedical Engineering paper described Precision's 1,024-channel thin-film microelectrode array slid onto the cortex through a sub-millimeter skull slit, avoiding full craniotomy, and tested in pigs and cadavers. The array records and stimulates from the same electrodes; a five-patient pilot during neurosurgery mapped sensorimotor and speech activity on the brain surface.

• 1,024-channel thin-film array one-fifth hair thickness; inserted through sub-millimetre skull opening.
• Records and stimulates from same electrodes at resolution hundreds of times higher than traditional arrays.
• Five-patient intraoperative pilot mapped sensorimotor and speech areas; tested in pigs and cadavers.
