"Ultrasound Revolutionizes Deep Brain Stimulation"

MIT researchers have developed a new method for deep brain stimulation using ultrasound instead of electrical impulses, delivered via a hair-thin fiber. This approach, tested in mice, can stimulate neurons to release dopamine, potentially offering a safer and more precise treatment for Parkinson's disease and other neurological disorders. The device, called ImPULS, avoids the corrosion and scar tissue issues associated with traditional electrodes and could also serve as a valuable research tool for studying the brain.
