Evidence that noninvasive sensory stimulation of 40 Hz gamma frequency brain rhythms can reduce Alzheimer’s disease pathology and symptoms, already shown with light and sound by multiple research groups in mice and humans, now extends to tactile stimulation. A new study by MIT scientists shows that Alzheimer’s model mice exposed to 40 Hz vibration for an hour a day for several weeks showed improved brain health and motor function compared to untreated controls. The MIT group is not the first to show that gamma frequency tactile stimulation can affect brain…
