While used in conjunction with Audio-Visual Entrainment (AVE) which is a technique that uses pulses of light and sound at specific frequencies to gently and safely guide the brain into various brainwave patterns. By altering your brainwave frequencies, you can normalize your mood, improve sleep patterns, sharpen your mind, and increase relaxation levels. There are also settings for Cranial electrotherapy stimulation (CES) which applies pulsed, alternating microcurrent (<1000 μA) transcutaneously to the head via electrodes placed on the earlobes, mastoid processes, zygomatic arches, or the maxillo-occipital junction. The U.S. Food and Drug Administration (FDA) granted approval in 1979 for CES for the treatment of insomnia, depression and anxiety. Controlled studies provide evidence that CES is effective for anxiety, headaches, fibromyalgia, smoking cessation, drug withdrawal symptoms, and (in some but not all studies) pain (see Bianco 1994; Klawansky et al. 1995; Kirsch 1996; DeFelice 1997; Gilula 2007; O’Connell et al. 2010 for review and meta-analyses).
