And what they've discovered that there's a particular pattern of brain activity called gamma activity. Gamma activity is one so-called wavelength of electrical activity in the brain, so not wavelengths of light, but wavelengths of electrical activity in the brain that can be restorative for certain aspects of learning and memory and can actually help create molecular changes in neurons that lead to clearance of debris and even reductions in age-related cognitive decline.
