  "account": "Severe paralysis can make communication difficult, with experimental brain-computer interfaces (BCIs) often focusing on either speech or movement. Scientists have now developed a brain implant that can control both speech and movement of a virtual avatar simultaneously. This innovation was detailed in the journal Nature Neuroscience on September 14. The implant, described as being implanted onto the sensorimotor cortex, allows users to control the avatar's speech and gestures in real time. While the technology is still in its early stages, it has the potential to enhance communication for people with paralysis or serve as a stepping stone to mind-controlled robotic prosthetics. The study involved two participants, one with paralysis from a stroke and the other with ALS. Each had an iPhone-sized device with 253 electrodes implanted onto their brain. The team trained computer models to decode the participants' thoughts as they formed phrases and gestures, and then mapped the brain activity to a personalized full-body digital avatar. In conversation tests, the decoders achieved an average of 85 percent accuracy in predicting gestures and 75 percent accuracy in predicting phrases. The stroke participant achieved 100 percent accuracy in speech and gesture decoding during three conversation tests. While the researchers acknowledge the implant's current limitations, they plan to expand the speech decoder's vocabulary and provide continuous control over individual body parts. The system may eventually help amputees control prosthetics with their minds and enable individuals to speak while performing everyday tasks like cooking.",
  "summary": "The experimental technology is still in the early stage and was fully tested in just two participants. But it could one day help people with motor problems communicate with more nuance or help them control robotic prosthetic limbs",
