Hemispheric Synchronization

"Many of the states of consciousness available through this technology have been identified as presenting unique hemispherically synchronized brain-wave frequencies. Although synchronized brain waves have long been associated with meditative and hypnagogic states, the binaural-beat process may be unique in its ability to induce and improve such states of consciousness. The reason for this is physiological. Each ear is "hardwired" (so to speak) to both hemispheres of the brain (Rosenzweig, 1961). Each hemisphere has its own olivary nucleus (sound-processing center) which receives signals from each ear. In keeping with this physiological structure, when a binaural beat is perceived there are actually two electrochemical synaptic waves of equal amplitude and frequency present, one in each hemisphere. This is, in and of itself, hemispheric synchrony of synaptic activity. Binaural beats appear to contribute to the hemispheric synchronization evidenced in meditative and hypnagogic states of consciousness. Binaural beats may also enhance brain function by enabling the user to mediate cross-colossal connectivity at designated brainwave frequencies.

...for each discrete state of consciousness, mind-consciousness interfaces with each area of the brain and each area resonates at a specific brain-wave frequency... F. Holmes Atwater. Journal of Scientific Exploration, Vol. 11, No. 3, pp. 263-274, 1997

"The two cerebral hemispheres of the brain are like two separate information processing modules. Both are complex cognitive systems; both process information independently and in parallel; and their interaction is neither arbitrary nor continuous (Zaidel, 1985). Because of this, states of consciousness (mindconsciousness interfacing with the brain) can be defined not only in terms of brain-wave frequency ratios, but also in terms of hemispheric specialization and/or interaction. Some desired states of consciousness may require facile inter-hemispheric integration, while others may call for a unique hemispheric processing style. An individual's cognitive repertoire and, therefore, his ability to perceive reality and deal with the everyday world, is subject to his ability to experience various states of consciousness (Tart, 1975). Binaural beats provide the tools for individuals to expand their ability to experience a wide range of mind-consciousness states.

"Each state of consciousness is not represented by one simple brain wave but involves a milieu of inner-mixing wave forms, a field effect. The reason for this lies in the structure of the brain itself. Not only is the brain divided horizontally into hemispheres, it is also divided vertically from the brain stem to the cerebellum, the thalamus, the limbic system, and the cerebral cortex. The cerebral cortex is further divided into such functional areas as the frontal lobes, the parietal lobes, the temporal lobes, and the occipital lobes. There are, of course, many other subdivisions of the brain which have not been mentioned.

"The critical point is that for each discrete state of consciousness, mind-consciousness interfaces with each area of the brain and each area resonates at a specific brain-wave frequency unique to that interface because it performs a localized function (Luria, 1970)."

Cerebral Optimization

Researcher Robert Cosgrove, Jr., Ph.D., M.D., an authority in pharmaceutics and biomedical engineering, commented on brainwave altering technologies:

"... with appropriately selected stimulation protocols [have] been observed by us to be an excellent neuro-pathway exerciser. As such we believe it has great potential for use in promoting optimal cerebral performance..."
