Electrical wave patterns that are generated in the human brain are called brainwaves. There are five distinct types of brainwave patterns and each pattern varies depending upon what level of conscious, subconscious or unconscious state the brain is in. These five distinct brainwave patterns all have different ways of perceiving, processing, learning and assimilating environmental stimulation. All five brain wave patterns are produced at all times. What determines which state the brain is in is dependent on which brainwave type is producing the most patterns. In other words, the dominant brainwave pattern determines the state the brain is in at any given moment. Using a light and sound machine will enable the participant to select a desired brainwave state which allows the individual to maximize his or her capabilities for achieving peak performance.
Brainwave frequency patterns can be measured with an electroencephalogram (EEG) and are described in terms of Hertz (Hz.) or cycles per second. The five generally accepted brainwave states and primary characteristics are:
There is a very high brainwave frequency pattern known as Gamma frequencies. These frequencies begin at thirty-five hertz. Some evidence suggests gamma brainwave frequencies are conducive to a peak performance state. Several light and sound mindmachines can generate lower gamma frequencies (<40Hz) and sometimes have gamma light and sound stimulation programs built into the unit. While in the gamma state the participant?s mental, emotional and physical state of mind feels extremely energized.
Beta brainwaves are the next highest frequency pattern. These frequencies range from thirteen to thirty-four hertz. There are three subcategories within the Beta brainwave frequency range: High Beta (18-34Hz), Beta (15-18Hz) and SMR (Sensorimotor Rhythm, 12-15Hz). Anxiety and emotional stress is likely to happen when high beta (18-34Hz) is the dominant brainwave state. But when beta (15-18Hz) is the dominant brainwave frequency the characteristics include being externally focused and feel ready for action. SMR is much like the beta brainwave state with generally speaking external focus while feeling a bit more relaxed. Within SMR is fourteen hertz, which is the same brainwave frequency that is the dominant brainwave when cats appear to be seemingly asleep, but will spring at a bug in the blink of an eye. 14Hz is an interesting frequency when experienced with a light and sound mindmachine like the Delight Pro with CES (Cranial-Electro-Stimulation) by Mind Alive. From your music library select what you feel like listening to and play it through your light and sound unit. The experience can be quite entertaining! One last thought about cats and accessing fourteen hertz at will: there was a study done a few years back that found cats are capable of producing 14Hz at will yet humans could not, unless of course the individual is familiar with brainwave focus training. The overall characteristics of beta brainwaves can include logical, analytical and intellectual thought, verbal communication and external awareness.
Ranging from eight to twelve hertz, Alpha brainwave frequencies are associated with being mentally alert while feeling calm and relaxed. Many believe that daydreaming is indicative of being in an Alpha brainwave state. Being deeply relaxed, inwardly focused, meditative commonly occur when in the Theta brainwave state. Theta brainwaves range in frequency from four to seven hertz. These brainwave frequencies are utilized for learning new information, high memory retention, creative thoughts and insights. Lastly, ranging from five-tenths to three hertz are the Delta brainwave frequencies. Delta brainwaves are the dominant brainwave frequencies during sleep and extreme relaxation.
