Researchers have developed a brain implant that could ultimately enable individuals to communicate solely through their thoughts. A team of neuroscientists, neurosurgeons, and engineers from Duke University in the US have created a brain prosthetic that can decode signals from the brain’s speech centre to predict the sounds a person is attempting to articulate. They say this breakthrough has the potential to revolutionise communication methods for those who are rendered unable to speak by neurological conditions. Dr Gregory Cogan is a professor of neurology at Duke University and one of the lead researchers on the project. He told Newsday that they have obtained “accuracy a little below 60%, which is about 35% better” than previous attempts. He adds: "As these devices get better…the hope is it will lead to almost complete restoration of speech.” (Picture: Shows an illustration of a chip implanted in a human brain. Credit: Getty Images.)
