I refer to my Re: Mol [From Bjorn Simonsen (2005.01.12, 12:25 EST)]
Are these comments about level 2, the sensing level, adequate? Can anyone
help me with my question marks? Are there other questions/comments about
level 2?
In the human organism (HPCT) there are many different input functions
receiving energy from Level 1. This energy comes from bunches of copies of
different first level perceptual signals. And they form new perceptual
signals at level 2. The only thing we know about these perceptual signals is
the frequency.
Level 2 relates to the state of perception signals in different groupings at
the first level. This is very well expressed in B:CP page 101: " A signal
leaving a second-order input function in the form of a neural current
represents a second level sensory abstraction in the nervous system.
......Each second-order perceptual signal is an analogue of a derived
quantity".
The nerve fibers carrying neural currents from first-order input functions
terminate in well-defined volumes of the brain stem known as sensory nuclei.
In the second order input function a second order perceptual signal is
formed as a weighted sum of different signals reaching it. The weighting is
a factor expressing the number of branches coming from the same neuron.
Mathematical expressed; p2 = k1*p1a + k2*p1b + .... Kn*p1m. Here p2 is the
second order perceptual signal in a selected control loop, k1 is the weight
telling how many branches coming from a certain neuron which have a
perceptual signal p1a and k2 is the weight telling how many branches that
come from another neuron with another perceptual signal, p1b.
The weights allow for some inhibiting first order signals and some first
order excitatory signals.
The different perceptual signals at level 2 have their input functions in
different placed sensory nucleus.
Different Input functions, comparators and output functions at level 2:
1. Perceptual signals having their starting points in all essentials in the
muscles; the spinal.
2. Perceptual signals having their starting points in the receptors in the
expansion of the rods and the cones: In the area of Horizontal cells,
Amacrine cells, Bipolar cells.
3. Perceptual signals having their starting points in the receptors in the
expansion of the taste buds: In the taste sensory nucleus in the Brainstem.
4. Perceptual signals having their starting points in the receptors
belonging to olfactory receptor neurones in the expansion of olfactory
epithelium in the nose: The smell sensory nucleus named Glomerulus.
The Sensing level in HPCT control the perceptions of different qualities.
Namely the qualities of colour, taste, smell, tactition, thermoception, the
perception of pain, Equilibrioception,. But I lack knowledge about the
receptors for tactition, thermoception, the perception of pain,
Equilibrioception.
Next week I presume I will continue with Level 3, Configurations. I already
now have problems with the configurations we can control as regards Hearing,
Tasting and Smelling.
