    Flickering Light Mobilizes Brain Chemistry That May Fight Alzheimer’s

    Article obtained from Photonics RSS Feed.

    Previous experiments using flickering light to treat neurodegenerative disease have shown promise, and now, researchers at the Georgia Institute of Technology (Georgia Tech) may have discovered how the flicker works. They found that exposure to light pulsing at 40 hertz (Hz) — 40 beats per second — caused the brains of healthy mice to release a surge of signaling chemicals that could help fight Alzheimer’s disease.

    Though conducted on mice, the new study is connected to human trials, in which Alzheimer’s patients are exposed to 40 Hz light and sound. Insights gained by the Georgia Tech team are informing the human trials in collaboration with Emory University.

    Prior work has shown that exposing mice to lights…
