This is reminiscent of Karl Pribram's holonomic theory.
Other
theories that depend on "waves" in sound and in EM frequencies as
communications between part of the brain to somehow achieve
consciousness both gestalt and subordinate among areas fancifully ignore
the structural complexity as well as a disconnect from known neural
networks and synaptic function. Frequencies measurable by devices
outside the brain or in surface contact are too broad, as they are
effectively measuring the "waste energy" that does not do work. Size
incompatibility dictates that such measurable activity can only be an
aggregate, or should I say aggravated, smoothed average of the myriad of
minor signals at the nano-level of structure. Gross averages, like
bundles of neurons, can show activity going from place to place, but
that is not structurally connected to the well known neural synapse
response and neural network functioning.
Brain complexity must smoothly unite functionality from the nano-level through intermediate levels to the macro-level.
The brain operates with and responds to more factors that the neurons. Nutrients,
hormones, inter-connectivity, temperature, and perhaps more can
influence the function of individual and groups of neurons. My
premise is simply that consciousness is not a "thing", it is not a
substance, and it is not a non-material substance. Consciousness
is the co-functioning of perception, representation, and reference, that
is explainable entirely in the cause-effect paradigm. My theses
explains the lowest core structures, the essential structure, of these
as interrelated, using a simple analogy between a limited brain and an
equally limited "computer". Perception, Representation, and Reference: Some Thoughts on an Essential Structure
Consciousness is experienced as a gestalt "state of mind" built on
continuing change. It can vary in strength to the point to appear to
disappear when we are totally involved in some activity. That makes
activity a primary factor in the brain structure functioning.
The earliest "knowledge" relevant to a theory of consciousness begins with Plato's Allegory of the Cave, The Republic, Book VII,
written in 517 B.C.E. The outside world is seen as shadows on the cave
wall. We are "conscious" of our selves and of the "shadows" we see,
both of which are different aspects of our brain's experiencing our self
and our environment.
The structural differential,
of general semantics fame, is a physical chart or three-dimensional
model illustrating the
abstracting processes of the human nervous system, patented on May 26,
1925, by Alfred Korzybski. It shows the environment level, the object
level, and the language level. We can not know the environment level,
as that is what happens before "the light hits our eyes. It represents
what caused the shadows on the cave wall. Our task is to expand our
knowledge of brain function to account for how we see and understand our
personal knowledge and our scientific knowledge, both continually
getting updated. What we experience consciously is our continuously
changing perception of ourselves in the context of our continuously
changing perception of our environment. In the third person, "figure on background", in the first person experiencing "activity on self".
Brain research has show that there are feed forward as well as feed back
circuits connecting memory to higher levels. These work so that our
slowly working brain is continually predicting what we are going to see
(experience) in the next seconds (feed forward), and it uses the
incoming data to tweak and correct the prediction. It does this through
many levels of visual (and other) abstraction. One retinal cell works
with others to turn on recognition of geometric line segments at various angles
with varying lengths. These neurons turn on and work with others to
recognize simple geometric figures. Many levels of this work with
memory to "identify" past experiences using more feed back and feed
forward. Eventually, a memory picture in the right place where I
put "it" shows my brain my cellphone. But, if it's not there, that picture
is washed out for the smooth table top also predicted.
I have a personal experience of this. When I was a lad of 18, I
joined the Navy. On my enlistment day, I was driven to Albany, NY, for
the beginning paperwork and being sworn in. After Dinner we were
hustled to a nearby military airport for our trip to Great Lakes,
IL, We arrived after midnight. We then marched from place to place
collecting out beginner uniforms and our ditty bag of personal
necessities. By 2:00 we were marched to a building that was all
dark. The only light was a couple of small red lights that showed no
discernible
illumination other that near the light itself. I was lead to a spot and
by touch "shown" a top bunk. Being exhausted I climbed in and
slept. Sometime around 5:30 I was awakened by a horrible noise,
which I found out later, was running a coke bottle around the inside of
an empty GI can, thunderously loudly, to wake us new recruits. I popped
up to a sitting position in my bunk, but I could not see anything
except whiteness. I started repeating loudly, "I can't see! I can't
see!" gradually my vision began to show graduated differences in the
whiteness, some areas getting darker, some areas getting brighter. In a
few
seconds more, the shades of light and dark began to take on shapes. The
light area became fluorescent lights hanging from the ceiling. The
darker areas faded into rows and rows of bunk beds, some people milling
around etc. By now the panic was fading. In my life I had never seen a
barracks nor bunk beds. I had never seen this site nor one like it. That
experience stayed with me for all my life. After the turn of the
century I read Jeff Hawkin's book "On Intelligence", with explanation of
how our slow wetware brain could come up with answers so fast,
introducing the memory predictive model. The more brain function I read
about the better I understood that what I had experienced on the morning
of
my first day in Navy Boot Camp was my slow brain having to build a new
memory without anything in memory to build it from. My best estimate
is that it took 5-10 seconds to establish the new memory so that
wherever I turned my head, my brain already had a memory picture
of that location ready for me to see.
Consciousness is figure on background of activity on self while
operating both dynamically in adaptive resonance (Jeff Hawkins) subsets
of neural nets, themselves dynamically changing, hierarchical organized
in memory predictive levels with feed forward and feed back interaction.
In this dynamic structure it is continuity of memory recall of self
against continuity of environment, both generated by memory prediction
corroborated and adjusted by sensory input in hierarchical stages. We
are only conscious of deviations from the expected memory predictions in both
environment and self at appropriate levels.
We are organisms that make a living by moving around. We also
project the future and prepare for it. The predictive model helps us
remember paths we previously followed, "especially if we found the
cheese at a particular location in the maze". Most of our success is
being able to remember sequences of activity through many steps.
Adaptive resonance functions to enhance our ability to mix similar
experiences and "adapt" to one we have not seen before. Feed forward and
feed back neural networks enable length while adaptive resonance allows
us to apply experiences to situations that are only similar.
Activity in neural nets can active others connected to enhance an
experience "extrapolate" at neural levels.
Have you ever seen a toad or a frog suddenly turn to one side to bring
the image of a potential meal into front center visual area? We don't
have to turn our heads to bring a remembered image into our virtual
relative front center. We can "think" an image moved to our front
center. We can also "set it aside" while we "think" something else
moved. That virtual front center is the center of a part of our
consciousness. Consciousness is activity in certain areas of the
brain. It can be nothing else. The brain has maps of the
body, the famous sensory and motor homunculus, distorted maps of our
body feeds into our active consciousness areas. Our brain creates
these experiences of prediction and corroboration with a delay. Our
virtual experience is in our brains constructed and projected after the
fact of that external "what is going on" that caused the experience.
