The frequency, ~ 10MHz, of GR/EM waves emitted from ionic fluxes through ion channels is equivalent to the carrier frequency in telecommunication. Brain waves are the modulating frequencies which may encode signal information. Physiological information from sensory inputs and memory retrieval is not encoded in alpha rhythms, but in the θ-nested-γ pattern (Chapter 36). Compelling evidence indicates that conscious perception of these information is accomplished through two stages. During the early stage, items (such as color and shape) are detected unconsciously and in parallel by the sensory system. In the later stage, attention is required to bind selected items, resulting in conscious perception of an entire scene with these items (Chapter 36).
From the physics perspective, the mind can be identified as the Bose-Einstein condensate (BEC) of gravitational (GR) and electromagnetic (EM) waves. Such BEC may also be called a geon, which is defined as an entity consisting of only GR and EM waves confined in a small region through their mutual attraction. An item in the preconscious stage could be encoded by the gamma-modulated GR/EM waves that are weakly bound to the geon. The item that can be consciously perceived is strongly bound to the geon. The role of theta rhythms is to organize gamma-encoded items so that they can be perceived as an integrated scene (Figure 37i).
It has been well established that "attention" is required to switch an item from the preconscious domain into the conscious domain and the alpha rhythms play a critical role in attention (Chapter 36). This physiological finding can also be explained at the physical level. Experiments have demonstrated that conscious perception depends on the harmonic alpha-theta coupling which may optimize the constructive interference between alpha-modulated and theta-modulated GR/EM waves, thereby enhancing the binding of the GR/EM waves modulated by the θ-nested-γ pattern to the geon which is formed by globally synchronized alpha rhythms. Hence, at a given moment, if the θ-γ powers that encode several items are strong, the increase of alpha power should promote these items to switch from the preconscious domain into the conscious domain.
