Audio-Visual Entrainment (AVE) is a technique that utilizes pulses of light and sound at specific frequencies to gently and safely guide the brain into various brain wave patterns. By altering your brain wave frequencies, you have the ability to boost your mood, improve sleep patterns, sharpen your mind, and increase your level of relaxation, all with the simple push of a button! AVE also increases brain health by increasing cerebral blood flow and stimulating beneficial neurotransmitters, such as serotonin, norepinephrine, and endorphins.†
