LIFU is a small, safe sound signal that produces a gentle, pulsing flow of acoustic waves to help different parts of the brain communicate with each other. Researchers want to understand how the mild, non-invasive brain stimulation affects speech relevant brain areas, which may in turn affect speech fluency and speaking-related brain activity in people who stutter.",[25,26],"Stuttering","Developmental Stuttering",[28,29,30],"Low Intensity Focused Ultrasound","Thalamus","Neuromodulation","NOT_YET_RECRUITING","2026-06-19",{"date":34,"type":35},"2026-06-25","ACTUAL",{"date":37,"type":19},"2026-06",{"date":39,"type":19},"2027-06",{"name":41,"class":42},"University of Michigan","OTHER",""]
