Background Information about Light & Sound Stimulation
(Excerpts from “Mind States: An Introduction to Light & Sound Technology”)
What Is An iLightz Light & Sound Instrument?
An iLightz light and sound instrument is a mind entrainment tool. The method by which this en-
trainment occurs is known as the Frequency Following Response (FFR). Through the use of au-
dio (headphones) and visual (eye frames with LEDs or RGB-based LEDchips) stimulation, par-
ticipants are gently guided into specific states of mind. Each audio beat and light pulse is a spe-
cific frequency. Our minds "think" in terms of frequency. Brainwaves change frequencies based
on neural activity within the brain, be it by hearing, touch, smell, vision and/or taste. These
senses respond to activity from the environment and transmits that information to the brain via
electrical signals. Hearing and vision are considered favorable senses for affecting brainwaves
safely. By presenting these beats and pulses to the brain, within a few minutes, the brain begins
to mimic or follow the same frequencies as the stimuli (the beats and pulses). This process is
referred to as entrainment. In essence, the iLightz light and sound instrument speaks to the mind
in it's own language- the language of frequency.
The Frequency Following Response that the mind experiences through light and sound stimula-
tion provides a focus for the brain. This focus safely quells any internal dialogue or "brain chat-
ter", and enables the participant to reach more quickly and effectively the optimum state of
mind targeted for the task at hand (i.e., energizing, learning, relaxing, etc.).
So a light and sound instrument can entrain your mind to experience different levels of your
consciousness. As such it is a tool, but it is a very enjoyable tool. For a whole new musical ex-
perience combine your favorite songs with an iLightz light and sound session. You can actually
see, as well as hear, the music as it travels along your brainwaves. It is also for exercising your
mind. After all, your brain is like a large muscle. Use light and sound to train your brain to run
faster and more efficiently; to show you how to find and access your "zone" and to help clean
up that mental fuzz that occasionally interrupts our mental clarity.
Here is a brief summary of the evolution of light and sound:
Humanity has been aware of how
outside stimulation can affect the mind long before recorded history. We can share that same
awareness by sitting around a campfire. Watching the flickering flames creates a soothing,
calming sensation within the mind. This same affect is also experienced with rhythmic drum-
beats. The continuous, repetitive beats tend to generate a calming affect, while faster repetitions
create a more energetic sensation. Within the twentieth century, researchers have developed this
awareness into highly beneficial instrumentation.
Although scientists knew flickering light and audio beats affected our frame of mind, they were
unable to prove how that interaction existed. Then in 1924, Hans Burger, a German psychiatrist,
published pictures depicting electrical activity of the human brain. From the discovery of these
"wavy" lines emerged a new scientific field called electroencephalography.
