The brain is both a chemical and electrical machine. It produces neurotransmitters to control electrical outputs throughout the body. In actuality the brain itself, is nothing more than a "dumb", electrical and chemical organ. It acts and performs like a computer. The brain is more related to the physical computer while vision as a processor; is related to the software that has been programmed to operate it.

A flickering light can cause mysterious visual hallucinations and alterations in consciousness. Modern scientific research into the effects of rhythmic light began in the mid-1930s when scientists discovered that the electrical rhythms of the brain tended to assume the rhythm of a flashing light stimulus, a process called entrainment. In the 1940's a neuroscientist Gray Walter used a strobe light to create flickering light (visual) stimulation, and noted that the brain wave pattern of the whole cortex was changed.. Since then many devices have been developed to entrain brain waves. Various types of visual stimulation means have been in use both clinically and commercially since the mid-1970s and currently there are a number of different manufacturers who make and sell these means. Published scientific and clinical studies have reported visual stimulations to be effective in inducing relaxation, reducing stress, reducing blood pressure, relieving tension headache, managing chronic pain, relieving insomnia, and reducing the discomfort of premenstrual syndrome. Visual stimulation means are currently being used by professional psychologists in their practices and by the general public for relaxation, stress management, Insomnia, mind expansion, accelerated learning and retention, breaking limiting beliefs, phobias, anxiety, sports training, promoting physical wellness. Throughout the 1970s and early 1980s, scientists found more fully how lights influenced the electrochemical activity of the brain. Flickering lights have been used for centuries to influence brain. Generally, the visual stimulation are designed to increase the EEG entrainment effect and to achieve some specific mind state.
