One brain implant could give people with paralysis a more expressive way to communicate
Researchers showed that a single high-density ECoG implant could decode attempted speech and upper-body gestures in parallel in people with severe paralysis, allowing two participants to control a personalized full-body avatar. Training the decoders on both isolated and concurrent behaviors improved performance across contexts and reduced false activations, offering proof-of-concept evidence for more expressive multimodal BCIs.
