Audio Visual Stimulation - Light/Sound Therapy

An AVS (Audio Visual Stimulation) system, Light and Sound Relaxation system or a "Mind Machine" is a microprocessor controlled
device designed to create relaxation or other mood changing effects through the use of sound and light stimulation. The user
selects a session, puts on headphones and stimulation glasses, and sits back and enjoys the experience, which can be for
relaxation, stimulation, meditation or just plain fun depending on the session.
Light/Sound systems blank out the complex visual and auditory stimulation the mind is constantly receiving and replace it with very
simple, rhythmic stimulation. The basic rhythms of the mental processes change in response.

I have been using AVS systems of a little over a year now and while I cannot fully explain how these systems work to control tongue
chewing they actually do work.  I recommend experimenting with different programs but the higher frequencies seem to work better
for me.
