B. How Are Frequencies Associated With Brainwaves?
Brainwaves are the electrical wave patterns generated in every person’s brain. These waves vary according to level of consciousness, sub-consciousness and unconsciousness and are characterized by four distinct types of brainwaves. Each of these electrical wave patterns have distinctly different ways of perceiving, processing, learning and knowing information (Hoiberg 1989). 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 a person to potentialize his or her capabilities towards achieving human excellence.
Brainwave frequencies are described in terms of hertz (Hz), or cycles per second, which are measured by an electroencephalogram (EEG). The four general categories of brainwave frequencies and their main characteristics are:
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 by some researchers to be part of the beta frequency category.
Beta brainwaves are the next highest frequency pattern, ranging from thirteen to thirty-four hertz, and can be separated into three sub-categories. The first is high beta, ranging from nine-teen to thirty-four hertz. 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. Mid beta is characterized by action, with focus on external surroundings. The third is SMR beta (Sensorimotor Rhythm), ranging from thirteen to fifteen hertz. While in this state, focus is also on external surroundings, but the individual is more relaxed than in mid beta. Within SMR is fourteen hertz, which is gaining attention from researchers and clinicians utilizing EEG/neurofeedback instrumentation. The true benefit of creating fourteen hertz in humans has yet to be determined, but a recent study at the University of California at Los Angeles found that felines can produce fourteen hertz at will, while humans cannot.
Generally speaking, beta brainwaves are characterized by logical, analytical and intellectual thinking, verbal communication and awareness of surroundings.
