Yes. In a Nature Neuroscience study published September 14, 2026, University of California, San Francisco researchers led by Samantha C. Brosler and Edward F. Chang showed that a single high-density electrocorticography (ECoG) implant can decode attempted speech and upper-body gestures simultaneously in people with paralysis.
Two BRAVO-trial participants controlled a personalized virtual avatar that produced speech and gestures such as wave, nod, shrug, and thumbs-up in the same real-time session, using parallel decoders on one 253-channel surface array. Training those models on simultaneous speech-and-gesture attempts improved performance versus training on isolated actions alone.
