How Are Pulsed Light and Sound Frequencies Associated With Brainwaves?

Brainwaves are the electrical wave patterns generated in every individual’s brain. These waves vary according to level of consciousness, subconsciousness and unconsciousness and are characterized by four distinctive types of brainwaves. Each of these electrical wave patterns contain distinctly different ways of perceiving, processing, learning and knowing information. All of these brain waves are produced at all times. However, a predominance of a specific desired brainwave state can be created at will, which allows an individual to maximize his or her capabilities towards achieving peak human excellence.

Researchers have proven that brainwave frequencies determine what brainwave state is being experienced at any given time by measuring the production of brainwaves through the utilization of EEG (electroencephalogram) instrumentation. The frequencies that produce these various brain states can be tracked on a computer monitor. As mentioned earlier, these frequencies are generated in every person's brain, and are the result of outside stimulation that has been passed to the brain via electrical signals from our different senses. Pulsed light and sound frequencies stimulate the neural activity of our vision and hearing, and can safely direct our minds to produce specific frequencies that are associated with the four general brainwave categories. That tidbit of information comes courtesy of Michael Hutchison back in 1992. Michael was a pioneer in light and sound frequency stimulation and an important contributor towards the growth and understanding of light and sound instrumentation.

 

Brainwave frequencies are described in terms of hertz (Hz), or cycles per second and are measured by an electroencephalogram (EEG). The four general categories of brainwave frequencies and their main characteristics are:

Delta brainwaves range from five-tenths to three hertz (0.5-3Hz) and are associated with being extremely relaxed, characterized by sleep.

Theta brainwaves range from four to seven hertz (4-7Hz), characterized by being deeply relaxed and inwardly focused. This brainwave state is also associated with rapid learning and the assimilation of new information with high retention, heightened motivation to activate goals, bursts of creativity, insight and new behavior patterns.

Alpha brainwaves are a frequency pattern ranging from eight to twelve hertz (8-12Hz). They most commonly occur when we are calm and relaxed, yet mentally alert. These brainwaves are also present during daydreaming.

Beta brainwaves are the next highest frequency pattern, ranging from thirteen to thirty-four hertz (13-34Hz), and can be separated into three sub-categories. The first is high beta, ranging from nineteen to thirty-four hertz (19-34Hz). When high beta is the dominant brainwave state, anxiety and stress are most likely to occur. The second sub-category is mid beta, with frequencies ranging from fifteen to eighteen hertz (15-18Hz). Mid beta is characterized by action, with focus on external surroundings. The third is SMR beta (Sensorimotor Rhythm), ranging from thirteen to fifteen hertz (13-15Hz). While in this state, focus is also on external surroundings, but the individual is more relaxed than in mid beta.

Generally speaking, beta brainwaves are characterized by logical, analytical and intellectual thinking, verbal communication and awareness of surroundings.

Gamma brainwave frequencies are a high frequency pattern beginning at thirty-five hertz. There has been some evidence that gamma frequencies are associated with states of peak performance. Most light and sound instruments have the capability to generate gamma frequencies. While in this brainwave state, sensations are centered on being mentally, emotionally and physically "charged" or extremely energized. These frequencies are the highest known brainwave patterns, but are considered to be part of the beta frequency category.
