When you reach out to produce the right word, your ears help you listen, and other parts of the brain produce the movements in your speech-related muscles. Individuals with speech impairment due to stroke often fail to either recognize errors in their production or make the proper adjustment. “These models help us predict the nature of the impairment,” Behroozmand said. “Studying the post-stroke population can advance our understanding about the neurological mechanisms behind these complex communication tasks,” he said. “Moreover, a better understanding of the neurobiological origins of stroke patients’ impairments can have many clinical implications for developing targeted interventions to improve patients’ communication skills.”
