  • Listening to low-pitched noise seems to induce high-speed brainwaves that break down protein plaques in the brain linked with Alzheimer's. The approach has had promising results in mice and is now being tested in people with the condition. Brainwaves are the result of large networks of brain cells firing rhythmically and in synchrony. People with Alzheimer's disease often produce fewer gamma waves, prompting researchers to experiment with ways of inducing this type of brain activity. Last year, Li-Huei Tsai's group at the Massachusetts Institute of Technology showed that exposing mice to a light flickering at a frequency of 40 hertz induces gamma waves in the part of the brain that processes information from the eyes, the visual cortex.
