Activating a specific brain wave through light and sound therapy enhances the release of peptides from interneurons, promoting the removal of Alzheimer’s-related proteins through the brain’s glymphatic system, according to recent research.

Research from MIT and other institutions is increasingly showing that light flickering and sound clicking at the gamma brain rhythm frequency of 40 Hz may slow the progression of Alzheimer’s disease (AD) and alleviate symptoms in both human volunteers and laboratory mice.

In a new study in Nature using a mouse model of the disease, researchers at The Picower Institute for Learning and Memory of MIT reveal a key mechanism that may contribute to these beneficial effects: clearance of amyloid proteins, a hallmark of AD pathology, via the brain’s glymphatic system, a recently discovered “plumbing” network parallel to the brain’s blood vessels.

“Ever since we published our first results in 2016, people have asked me how does it work? Why 40 Hz? Why not some other frequency?” said study senior author Li-Huei Tsai, Picower Professor of Neuroscience and director of The Picower Institute and MIT’s Aging Brain Initiative. “These are indeed very important questions we have worked very hard in the lab to address.”
