Light and Sound Mind Machines are devices that use sensory stimulation to induce specific effects on your mind to change how you feel.
Some of these mind machines use light for example, while others combine the use of light and sound, and yet others use electrical stimulation.
Somestimes called an AVS (Audio Visual Stimulation) system, light and sound machines contain are 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 and sound mind machines can change your mind state by affecting your brainwaves.
This may sound 'fantastic' or magical - but the changes they make to brainwaves are easy measure.
These changes result from a scientific principle called entrainment.
The entrainment principle is the tendency for two oscillating bodies to lock into phase. Entrainment happens when the vibrations from
two or more rhythm cycles stimulate each other into a synchronization.
It is called brainwave entrainment or the 'frequency following response' when it is used to change brainwaves.
The brain is constantly being stimulated, and our neurons ceaselessly fire off and on. This firing is the brain
responding to stimulation. Neurons can even fire in rhythm to the beat of music being listened to.
After the brain has been responding to the continous stimulation of a frequency for around 5-6 minutes, it begins to generate the same rhythm on its own.
When the lights and sound from our machines pulse at the speed of normal brainwaves when a session begins, they quickly synchronize.
Your brainwaves will then follow as the light and sound stimulation shifts into the frequencies of another mind state. This is called
the frequency following effect, or entrainment.
Light and sound mind machines have a powerful impact on the brain. Because of this, these methods can benefit
medical and psychological problems.
