Thoughtless-ness cannot exist. Consciousness as thought exists only through its active expressions and manifestations as parts of its Creation.
Theta waves are of a lower voltage and higher frequency (4 to 8 Hz) and show up throughout all the regions of the outer shell of the human brain called the cerebral cortex in an disorganized and spurtive manner. Theta waves originate probably in a very deep inner seated area of he brain called the hippocampus. Animals excluding primates show very large and constantly organized production of Theta waves that are easily recorded at the level of their cerebral outer cortex. Beta waves are of an even lower voltage and faster vibratory rate (10 to 20 microvolts and 14 to 30 Hz).
The vibratory scheme of the brain seems to imply, therefore, by virtue of the mathematical construct of periodic waves (Fourier transform), that the higher amperage and slower waves of Theta are a prelude to the production of smaller and faster vibrations. Or, in layman terms: Delta probably originates Theta that originates Alpha that originates Beta
In mammals and many other species, the brain is the major processing interface between the reality of thought and the sensory perception of matter. The brain is the seat of sensory input/output defining and framing our perception of space/time reality. Visual, auditory, olfactory, tactile etc. sensory perceptions originate from it.Sensory experiences are coherent and subjective. Life, as a perception of linear space/time causal realities, is but a grand illusion created by our senses.
Reality, which is our perception of space/time, is perceived through our senses, and each individual’s sensory perception is unique. Our senses condition us and define our needs. Thus, we cannot avoid catering to them. When all senses are gone, life ends. The space/time dimension of reality is then over, because it can no longer be perceived. All individuations of thought operating within the space/time continuum are different in order to keep the challenge great and life interesting. The challenge is in these realizations and in the ensuing behavior modifications they will hopefully bring about.
It is only the sensory (material phenomenal) world that binds thought to the external realities of space/time. Thought, in itself, is not bound by either. In a modern digital computer, the linear multimedia output of information is performed by the input/output cards (digital/analog conversion) attached to it (graphics, audio etc..). We can connect to them through video screens and speakers. We can then see and hear information presented in a linear palatable fashion to our linear physical senses processed in our brain. Nevertheless, the digital computer uses nonlinear processing methods and stores memory within its memory cells in a random (nonlinear) accessible fashion. One can see electrical activity within these input/output cards when information transits through them, and they also cease to work properly if they are damaged. This is exactly what the brain does: it is a transducer and decoder of nonlinear information (digital-like) into linear (analog-like) sensory data.
That information is then processed by the individual's restricted mind. Information only passes through it. As a feedback mechanism, thought (MIND) makes decisions based upon the linear 3D sensory data experienced. And based on these decisions, more sensory information is then projected to each and every thinking individual.
