A bioRxiv preprint reports that intracortical signals predicted movement onset 250–400 milliseconds ahead in three people with tetraplegia. Participants reported intending to act on 88% of trials when a virtual opponent interrupted them.

A Nature Neuroscience study used a single high-density brain implant to decode attempted speech and upper-body gestures in parallel from people with paralysis. The outputs drove a virtual avatar and displayed speech as text, while context-inclusive training improved decoding across isolated and simultaneous tasks.

Researchers used a 253-electrode cortical implant and artificial intelligence to decode intended speech and gestures simultaneously in two people with severe paralysis. The proof-of-concept system displayed words as text and represented gestures through a personalised animated avatar.
