Brain Stimulator: Visual, Haptic, and Auditory Brainwave Entrainment

The use of brainwave entrainment has increased in popularity following recent articles such as Sensory-Evoked 40-Hz Gamma Oscillation Improves Sleep and Daily Living Activities in Alzheimer’s Disease Patients.

Brain waves are oscillating electrical voltages in the brain that can be recorded from electrical activity on the scalp using electroencephalography (EEG) technology. The most widely recognized brain waves are gamma, beta, alpha, theta, and delta. Frequencies of brainwaves are associated with different states of arousal, emotion, thought, and more. For example, low-frequency delta waves are present during deeper stages of sleep, whereas higher frequency beta waves are most salient during states of arousal.

Brain Stimulator is an Android app I developed that generates rhythms of stimuli to synchronize brainwaves to a specified frequency. For example: By flashing a light 40 times per second (40Hz), 40Hz gamma brainwave activity is enhanced, especially in regions that process visual information. Thus, brainwaves synchronize, or “entrain”, with the flashing light stimulus.

By utilizing hardware on your mobile device, Brain Stimulator can entrain your brainwaves to a specified frequency.

Do not use brain stimulator if you have a history of seizures, epilepsy, or are sensitive to flashing lights/colors. Please read the full terms of service before using this application:
