ANNOTATION:
Theory: How a neuronal fiber holds a concept.

As a nerve fiber you can be either on or off, energized or not energized, and at states in between, but you do not HOLD your concept in the sense of CONTAINING it. Just as no "homunculus" sits in your head, likewise no "conceptunculum" lies in a fiber.

Let us say that you are the long neuronal fiber of the concept "(to) eat." The word "eat" is NOT inside your fiber-body, but rather you CONTROL the word "eat" at various temporal points in your life-long auditory memory channel. If you as the "eat" fiber become fully energized, or "on," you will fire signal-spikes across associative tags stretching from your own synapses over to the recall-synapses of forms of the word "eat" in the auditory memory. Then your internal ear will hear, that is, THINK, the word "eat." You as a concept-fiber will have caused part of a THOUGHT -- an expression of an IDEA.

Let us back up to WHY you become active in co-creating a thought. Both BLANKET inputs and SINGLE inputs may partially or fully energize you -- turn you "on."

BLANKET (semi-activating) signals come from other neuronal fibers that are part of the SYNTAX control architecture. In your case, when the Chomskyan syntactic mind is trying to generate a thought or sentence to the effect that "X eats Y," a node on the neuronal syntactic tree sends out a BLANKET signal which partially activates many -- perhaps ALL -- verbs in the vocabulary of your host mind. The host mind is grasping for (French:) "le mot juste" -- the best word to express the idea of consuming something with the mouth.

SINGLE inputs come to you from SINGLE sources, such as from what- ever NOUN your host mind is thinking about. Let us say that you as the nerve-fiber for "eat" have been active in the past with hundreds of different subject nouns such as "lions" and "tigers" and "bears." If you have already been semi-energized by a BLANKET signal from a syntax node trying to FLUSH out an appropriate verb, and if a SINGLE spike comes to you from a particular subject such as "bears," then you will go into full activation and you will send out your own "SEMI-ACTIVATING" signals to other concept fibers.

You will semi-activate ALL the other (object) concept fibers ("Y") with which you have ever been involved on the basis of "X eats Y." If "bear(s)" is fully active, and if "eat" is fully active, then many concept fibers of things that bears typically eat will be SEMI-ACTIVATED. What pushes a particular "object" concept fiber "over the top" into the FULL ACTIVATION that rouses a WORD-string within the auditory memory channel? The TIME and CIRCUMSTANCE of SPREADING ACTIVATION cause a particular OBJECT concept to turn on. Although you as the concept fiber "eat" have been active with many subjects and many objects, it was always at a particular time in the life-history of your host mind, and so the JOINT influence of the BLANKET syntax signal and the single ONE-TIME subject signal from the "bears" concept will SELECT only that particular "object" fiber (for associative activation) which has SIMULTANEITY tags stretching from "X" to "Y" in the "X eats Y" nexus of association.

This revolting, shocking proposition says that our minds store ideas and knowledge as a temporal, that is, TIME-BOUND nexus of associative tags, typically centered around a linguistic verb that links to subject-concepts and to object-concepts. Knowledge is represented within a brain as SIMULTANEOUS links among the
The Mentifex mind diagram below shows only one fiber per concept, but similar concept-fibers holding the same concept are REDUNDANT in MASSIVE PARALLELISM lest perish the thought if its underlying concept fiber should die -- as brain cells are wont to do. GANGS of concept fibers holding a single concept act logically as ONE.
