Brain zaps may restore speech and hand movement in stroke survivors

This study tests whether temporarily stimulating a specific part of the brain can improve hand, arm, and speech abilities in people who had a stroke at least 6 months ago. Ten participants will have a thin wire placed deep in the brain for less than 30 days to deliver mild electrical pulses. The goal is to see if this approach is safe and which movements or speech improvements it can produce, laying the groundwork for future rehabilitation tools.
