US scientists invent micro-LEDs that treat neurological diseases

Recently, scientists from the University of Illinois invented a miniature LED that can easily pass through tiny pinholes. Experiments have shown that this miniature LED can effectively perform deep brain stimulation through wireless operation and has a certain effect on nervous system diseases such as movement disorders.

In the experiment, the researchers placed an LED probe into the mouse's brain, and then used light pulses to stimulate neurons in a part of the brain's reward pathway in mice. After receiving this LED pulse stimulus, mice will spend more time in the Y-shaped maze, as if they know how to get food rewards in the maze.

John Rogers, one of the experimental leaders, said that this new miniature LED will effectively improve the treatment of neurological diseases, and will help medical personnel accurately insert LED light sources, sensors, and other medical components into the brain nerves of patients. . If research is fully successful and widespread, this micro LED medical device will be able to cure a range of neurological disorders including dyskinesia.
