Massachusetts Institute of Technology have created a fiber that uses ultrasound to simulate neurons in the brain

Watch this video report on a new breakthrough in Parkinson’s treatment. Traditionally, deep brain stimulation uses electrodes to deliver electrical pulses to the brain, but these electrodes can corrode, causing tissue scarring and eventually requiring removal. Now, researchers at MIT have developed a fiber that uses ultrasound instead of electricity to stimulate neurons in the brain. This fiber generates high-frequency sound waves that activate brain cells and help reestablish broken neural connections, which can significantly reduce tremors. This innovative treatment has already improved motor control for Parkinson’s patients, helping them regain more control over their movements and lives. There’s also potential for it to aid in memory restoration, though more testing is needed before it can be widely available. Researchers hope to make this treatment available within the next five years.
