Meditation Mind Machine History:
Meditation Mind Machine History shows that modern technology has enabled scientists to study the effects of rhythmic light and sound on the brain. They are now able to harness light and sound to achieve greater effects. In the mid 1930s scientists discovered the brain rhythms tended to mimic the rhythm of a flashing light. In the 1940s British neuroscientist W. Gray Walter used an electronic strobe and EKG equipment to investigate what he called “flicker phenomena,” the trance-like states of profound relaxation and vivid mental imagery.
In the 60s and 70s scientists discovered that flicker effects at certain frequencies seemed to have amazing beneficiary effects, including: increased IQ scores, enhanced intellect, and greater synchronization between the creative and analytical parts of the brain. During this time, scientists discovered that adding auditory stimulation increased the effect of rhythmic light.
In the early 70s, Jack Schwartz, known for his feats of self healing, began selling a devise called “ISIS” Schwartz’s devise was a set of goggles with variable frequency lights mounted with rhythmic lights and sounds reported to produce heightened mental states. In 1974, Seymour Chakras, a scientist at City College of New York obtained the first patent on a combined light and sound stimulation machine but it was never put into commercial production.
In the 1980s technological advances in micro electronics enabled home inventors to put together surprisingly complex sound and light devices. These produced a rich assortment of tones, chords and beat frequencies, and a selection of light flash patterns that allowed users to choose the combination of light and sound appropriate for their needs. Now there are over 20 light and sound machines in commercial production.
