“Within our own bodies, we are constantly locking in our own rhythms. Our heart rate, respiration and brain waves all entrain to each other.” Johnathon Goldman Each brain center generates impulses at a specific frequency, based on the predominant neurotransmitters it secretes… In other words, the brains internal communications system - its language, if you like - is based on frequency Dr Margaret Capel. Like sound waves, the brain has its own set of vibrations it uses to communicate with itself and the rest of the body; EEG equipment distinguishes these waves by measuring the speed with which neurons fire in cycles per second. At their boundaries these waves can overlap somewhat, merging seamlessly into one another, so different researchers may give slightly different readings for the range of cycles per second. Rate of cycling determines the type of activity, kindling wave after wave over the whole surface of the brain, by igniting more neurons. BETA waves (14 cycles per second and above) dominate our normal waking state of consciousness when attention is directed towards cognitive tasks and the outside world. Beta waves range between 13-40 Hz. Gamma (above 30 Hz) represents hyperarousal. The Beta wave is associated with peak concentration, heightened alertness and visual acuity. Nobel Prize winner, Sir Francis Crick and other scientists believe that the 40Hz beta frequency may be key to the act of cognition. ALPHA waves (7-13 cycles per second) are present during dreaming and light meditation when the eyes are closed. As more and more neurons are requited to this frequency, alpha waves cycle globally across the whole cortex. This induces of deep relaxation, but not quite meditation. In Alpha, we begin to access the wealth of creativity that lies just below our conscious awareness. It is the gateway, the entry point that leads into deeper states of consciousness. Alpha is also the home of the window frequency known as the Schumann Resonance, which is the resonant frequency of the earths electromagnetic field. SR waves propagate with little attenuation around the planet. When we intentionally generate alpha waves and go into resonance with that earthy frequency, we naturally feel better, refreshed, in tune, in synch. It is, in fact, environmental synchronization. THETA waves (4-7 cycles per second) occur most often in sleep but are also dominant in the deepest state of mediation (body asleep/mind awake). The optimum level for deep thought is this realm of Theta. In Theta, our senses are withdrawn from the external world and focused on the mindscape, internally originating signals. Theta waves are associated with mystery, an elusive and extraordinary realm we can explore. It is that twilight state which we normally only experience fleetingly as we rise from the depths of delta upon waking, or drifting off to sleep. In theta we are in a waking dream, vivid imagery flashes before the minds eye and we are receptive to information beyond our normal conscious awareness. Theta has also been identified as the gateway to learning and memory. Theta meditation increases creativity, enhances learning, reduces stress and awakens intuition and other extrasensory perception skills. DELTA waves range between 0-4 Hz. Delta is associated with deep sleep. In deepest meditation and dreamless sleep, Delta waves are generated. Each of these brainwave frequencies serves an important function. DELTA waves confer a suspension of external existence and provide the most profound feelings of peace. In addition, certain frequencies in the delta range trigger the release of growth hormone beneficial for healing and regeneration. This is why sleep, deep restorative sleep is so essential to the healing process. nwbotanicals.org/oak/newphysics/schumann/schumann.htm
