Brains of Sand           6            From Movement to Consciousness  (this section still under construction)

The first model of animal intelligence presented was the GOLEM - Figure 6.1 upper left. In the GOLEM, the afferent (input) channel consisted of two stages, the P-stage (named after the parietal lobe) and the T-stage (named after the temporal- pertaining to the temples, not time- lobe). The GOLEM's efferent (input) channel also consists of two stages, the L-stage (named after the limbic system/circuits) and the F-stage (named after the frontal lobe).

There is one surprise when we examine the GOLEM - why does the L-lobe occupy such a dominant role? Can we change the diagram to reflect its primacy,^ esp. w.r.t. the fact that it is the source of all agency, because it encapsulates and embodies the changing cybernetic differential quantities (the Drive State Differentials, or DSD's). 

The second model of animal intelligence presented was the TDE - figure 6.2 lower left. In the TDE, the L-lobe is given a central, gubernatorial location**. In the TDE model, all output occurs through the P-lobe, via common global displacement codes*. Motor quantities are determined locally, via goal-oriented differential-compensatory feedback loops. This is nothing more than the common-or-garden servomechanism, now dressed in Emperor's Clothes.

The importance of this step cannot be overstated. The 'four-square' GOLEM is not readily amenable to fractal scaling, whereas the TDE is easily converted to its global counterpart, the TDE-R, with no change to the gubernatorial order (ie the L-lobe is still central and has causal primacy).

The primacy of the L-lobe leads directly to the insight that it is emotion and not consciousness which is the mind's true lingua franca


*William James, so-called Father of Psychology, was the first to understand the critical importance of the idea of 'common coding'.

**note the similarity in both form and function between the TDE's four lobe setup, and an epicyclic (planet-sun-ring) coaxial reduction gearset.

^We were fortunately able to answer this question in the affirmative

The TDE model (figure 6.3 at left) demonstrates how thought and language are two sides of the same coin. The left side of the CNS is usually associated with language, while the right side is associated with emotion.

Consider first the meaning layer, fractal level 3. The red line represents meaning production (syntax), passing through Broca's Area, while the yellow line represents meaning representation (semantics).

While the red and yellow lines represent meaning content, the blue and green lines represent meaning context. ie emotion. The blue line encodes the prosodic part of meaning production, while the green line encodes the prosodic part of meaning representation.

Figure 6.4

The GOLEM and QOLEM functions are derived from the complex operations of the cyberdynamic servomechanism shown at upper left. 

The global GOLEM (or TDE-R, which is its L-centric* equivalent) is oriented perpendicularly to the local GOLEMS (or TDE's). That is, at the global scale, the F-lobe-to-T-lobe axis goes from left to right**, while at the local scale, the F-lobe-to-T-lobe axis goes from front to back, aligned with the sagittal mid-plane. - shown at upper left.

The L-centric form of the GOLEM is the TDE- the circular shape with the L-lobe at its center, drawn this way because the L-lobe is the causal locus, the place where all agency is generated.

The global F-lobe is the entire Left Cerebral Hemi (LCH), which is where Tulving locates episodic memory, while the global T-lobe is the entire Right Cerebral Hemi, which is where Tulving locates semantic memory. Together, episodic (ie narrative) and semantic memories form Tulving's declarative memory layer. 

  

Figure 6.5

Note that the QOLEM diagram contains some useful ambiguities. For example, the top-right sector which represents CxI (Conscious AND Involuntary) sub-states contains BOTH sensory stimuli from self AND non-self sources. Stimuli from non-self sources fall into the Involuntary class automatically (you can only have voluntary control over your own actions). However, if the items in this quadrant are self-generated, then they must be automatized (instinctual or previously learned) sensory inputs.

This new abstract state machine (ASM) can represent subjective states of mind (also known as qualia, hence the acronym QOLEM). Some of the state transitions between the sectors of the QOLEM correspond to familiar learning paradigms. Furthermore, the capacity of this architecture to support phenomenal states does not rely on a circular argument, or on so-called 'emergence' - rather, it is a direct result of a specific type of mechanism - the orthogonalisation of local and global decussations.


The golden rule of reverse engineering is to work from the 'top down', sometimes described as 'working from the outside going inwards'. If the mechanism described above is correct, then the next task is to search for a circuit design which (a) is plausible from the evolutionary stance, and (b) incorporates decussation architectonics, ie involves orthogonalisation of complementary canalisation (sensory and motor) functions. 

Figure 9 depicts the neural connections in the simplest biomechanical system, the biceps muscle/elbow joint. By using this as the architectonic canon (ie its Repeating Fractal Unit, or RFU), both condition (a) and condition (b) above are, prima facie, satisfied.
