I refer to my Re: Mol [From Bjorn Simonsen (2005.01.12, 12:25 EST)]
Are these comments about level 3, the configuration level, adequate? Can
anyone help me with my question marks? Are there other questions/comments
about level 3?
Level 3 is the configuration level. I think Bill expressed himself in one to
me logical way, when he described level 3 as a level with invariant
qualities relative to the sensations at level 2.
It is easy to understand that a certain hand-body configuration is a set of
kinaesthetically sensings with varying levels of effort (maybe also with
some intensity scalars). It is also comprehensible that visual forms or
objects are a weighted sum of different shapes, colours and maybe also
intensities.
I also understand that ringing, humming, clicking, rushing, chirping,
buzzing, knocking or rumbling are weighted sums of tones, pitches, timbres
and loudness. Equivalent phonemes and sound-shapes of different musical
instruments or human voices are hearing configurations.
Is it correct to say that the lemon taste is a configuration?
Are there any configuration qualities as regards tactition and
Equilibrioception ?
Different Input functions, comparators and output functions at level 3:
* Perceptual signals having their starting points in all essentials in the
muscles have their input functions, comparators and output functions in the;
cerebellum and thalamus and in the sensori-motor area of the cerebral
cortex.
* Perceptual signals have their starting points in the receptors for vision,
hearing, smell, taste touch and other sensations have their input functions,
comparators and output functions in the midbrain.
B:CP page 116 suggest that cerebellar damage may cause in tremor because
control systems become unstable. And the instability is of second order. I
don't understand this very well. Why should instability at the sensing level
cause tremor around three cycles per second?
Other literature tells me that the organ substantia nigra (maybe a forth
level organ in HPCT ?) produce dopamine, When substantia nigra is damaged,
dopamine is not carried to the basal ganglia where we find the sensori-motor
area of the cerebral cortex. And when these third level neurons don't get
dopamine (transmitters) in their pre synaptic areas, control at the fourth
transmission level doesn't function. But maybe I misunderstand Parkinsons
disease?
As mentioned above the perceptual signals that have their starting points in
all essentials in the muscles have their input functions, comparators and
output functions for the configuration level in the cerebellum.
Equilibrioception is the perception of balance and I guess the standing
position is a Configuration. I think we control our perception of balance at
the third level in the cerebellum. This is important, but not so important
that the control of the perception of balance is for birds and fishes. Look
at the birds at the telephone wire. Therefore we find a relative much
greater cerebellum in them.
Dependent on brain damage and where the damage is, people perceive and don't
perceive different images. Some see objects (level 3), but they don't record
movement (level 4). Some see movement (level 4), but no objects (level 3).
If we place them in front of a ball, they don't see the ball. But they see
something when the ball is moving.
I think this fit in with HPCT's system with sensing, category and
transmission.
If an organism could not control higher levels than configuration, the
organism and all organs in the organism would be locked.
I see that this type of HPCT passage is not very interesting. That is
understandable. But I have questions when we reach the sixth level and
higher, therefore I continue with one level each week. Contemporary I study
the Visual system http://webvision.med.utah.edu/ and in a month I guess I
have more to say at the three, four lowest levels.
