The Interrupted Self | |
http://samvak.tripod.com/psychophysics.html The fundament of our mind is the mental map we create of our body ("Body Image", or "Body Map"). It is a detailed, psychic, rendition of our corporeal self, based on sensa (sensory input) and above all on proprioception and other kinaesthetic senses. It incorporates representations of other objects and results, at a higher level, in a "World Map" or "World Image". This World Map often does not react to actual changes in the body itself (such as amputation - the "phantom" phenomenon). It is also exclusionary of facts that contradict the paradigm at the basis of the World Map. This detailed and ever-changing (dynamic) map constitutes the set of outer constraints and threshold conditions for the brain's operations. The triple processes of interaction (endogenous and exogenous), integration (assimilation) and accommodation (see here "Psychophysics") - reconcile the brain's "programmes" (sets of instructions) to these constraints and conditions. In other words, these are processes of solving dynamic, though always partial, equations. The set of all the solutions to all these equations constitutes the "Personal Narrative", or "Personality". Thus, "organic" and "mental" disorders (a dubious distinction at best) have many characteristics in common (confabulation, antisocial behaviour, emotional absence or flatness, indifference, psychotic episodes and so on). The brain's "Functional Set" is hierarchical and consists of feedback loops. It aspires to equilibrium and homeostasis. The most basic level is mechanical - hardware (neurones, glia, etc.) and operating system software. This software consists of a group of sensory-motor applications. It is separated from the next level by exegetic instructions (the feedback loops and their interpretation). This is the cerebral equivalent of a compiler. Each level of instructions is separated from the next (and connected to it meaningfully and operationally) by such a compiler. Next follow the "functional instructions" ("How to" type of commands): how to see, how to place visuals in context, how to hear, how to collate and correlate sensory input and so on. Yet, these commands should not be confused with the "real thing", the "final product". "How-to-see" is NOT "seeing". Seeing is a much more complex, multilayered, interactive and versatile "activity" than the simple act of light penetration and its conveyance to the brain. Thus - separated by another compiler which generates meanings (a "dictionary") - we reach the realm of "meta-instructions". This is a gigantic classificatory (taxonomic) system. It contains and applies rules of symmetry (left vs. right), physics (light vs. dark, colours), social codes (face recognition, behaviour) and synergetic or correlated activity ("seeing", "music", etc.). Design principles would yield the application of the following principles: 1. Areas of specialization (dedicated to hearing, reading, smelling, etc.) 2. Redundancy (unutilized over capacity) 3. Holography and Fractalness (replication of same mechanisms, sets of instructions and some critical content in various locations in the brain). 4. Interchangeability - Higher functions can replace damaged lower ones (seeing can replace damaged proprioception, for instance). 4. Two types of processes: Rational - discrete, atomistic, syllogistic, theory-constructing, falsifying Emotional - continuous, fractal, holographic By "fractal and holographic", we mean: 1. That each part contains the total information about the whole 2. That each unit or part contain a "connector" to all others with sufficient information in such a connector to reconstruct the other units if lost or unavailable. | |
