Gamma brain stimulation (around 40 Hz) is performed using light pulses. To perform theta brain stimulation (around 7 Hz) without perceptible flicker, the light source is also strobed at 47 Hz (also within the gamma range). The brain perceives the 40 Hz and a subtraction frequency of 7 Hz (in the theta range). The combined gamma and theta wave stimulation of the brain may be used for preventing or treating brain disease or sleeping disorders. The particular stimulation frequencies and their phases create neuronal gamma-theta coupling in the brain that has been shown to have positive effects on memory, Alzheimer's disease, motor skills, and other functions. Other gamma and theta frequencies, creating gamma-theta coupling in the brain, are also beneficial. The phase of the light pulses is also dynamically controlled using feedback to maximize theta-gamma coupling in the brain.
