‘Multifunctional’ brain implant translates speech and gestures in real time

A Nature news report describes a proof-of-concept study published in Nature Neuroscience in which a single surgically implanted 253-electrode array covering a fairly large area of the sensorimotor cortex, combined with artificial intelligence, simultaneously decoded attempted phrases and attempted or imagined gestures in two participants with impaired speech and movement after a brainstem stroke or with amyotrophic lateral sclerosis, producing on-screen text and driving a personalized animated avatar within seconds of the user’s intent, thereby translating both verbal and non-verbal communication through one implant.
