Light and Sound Stimulation Help Regrow Brain’s ‘White Matter,’ Protects Against Neurodegeneration: Animal Study

Demyelination, which occurs when nerves lose their protective fatty coating, is the cause of several severe and incurable neurodegenerative diseases. In a recent animal study, researchers at the Massachusetts Institute of Technology (MIT) found a way to possibly recover the lost fatty coating by stimulating the brain to release more gamma brain waves. Using patterned light and sound paced at 40 Hz, mice were induced to produce gamma brain waves, Li-Huei Tsai, Picower Professor at The Picower Institute for Learning and Memory and the Department of Brain and Cognitive Sciences at MIT, told The Epoch Times. “The neurons in the animals respond at that exact frequency and generate brain waves at that frequency.”...
