How light and sound technology works

Follow the waves

Since ancient times man observed that flickering lights and rhythmic sounds often produced a relaxed state of mind. Around 200 A.D. the astronomer Ptolemy noted that when a person looked toward the sun through the spokes of a spinning wheel, the flickering sunlight caused patterns and colors to appear and produce a feeling of euphoria, even though the eyes of the observer were closed.

Modern scientific research has verified this phenomenon: the brain tends to assume the rhythms of a flashing light stimulus, known as the frequency following effect. Scientists have also shown that certain states of consciousness tend to be associated with certain brainwave patterns. For example, when we are in a deeply relaxed state of mind our brainwaves emit an electrical frequency of 4–8 Hz per second.

The basic idea behind light and sound technology is that the gentle pulses of light can lead one to the state of mind associated with that particular frequency range. The various pre-programmed “sessions” found in the Mind’sEye and Galaxy can be used for different purposes, including meditation, stress reduction, accelerated learning, restful sleep, increased creativity, and goal setting.

In actuality, we continually receive stimuli that affects our mental state, whether it’s music, TV, the internet, or the spoken word. When one begins to understand their moods and performance states are really a reflection of the mental states they are in, then adjusting that state in a conscious fashion seems the natural thing to do.

The beneficial effects of light and sound have been clinically tested and verified for over 50 years. Many physicians, mental health professionals, and educators routinely use devices like the Mind’sEye and the Galaxy to help their clients. With gentle pulses of light and sound you can attune your mind to a desired state at the touch of a button.
