Definición: Los mecanismos asociativos deben tener alguna explicación. Uno puede imaginar señaladores o etiquetas que permitan asociaciones o mecanismos tipo Hopfield de mínima energía de cómputo o valles termodinámicos. Esos señaladores son las fijaciones de la memoria de largo alcance
Each sensory memory channel is like a pipeline full of nodal fibers.The nodal fibers are already there, genetically provided and ready to receive engrams of memory. The pipeline is gradually filling up with memory slices all through your lifetime. The memory-slices are so densely packed that you could live to be over a hundred years old and not run out of fresh, unused, tabula rasa memory locations. The gradual fixation or consumption of memory-slices is like a slow burning fuse, so long that it takes over a hundred years to burn to the end. Even if you did run out of fresh memory-spaces in your old age, you would still function as an intelligent mind with full retention of your many decades of old memories and with the loss of only your ability to remember each passing moment of the present. You could still speak, for instance, several languages and do anything else that you learned to do before your tabula rasa memory ran out. This assertion is another one which ought to be judged in the light of the total mind-model.
Meanwhile, as the signal of the sensed feature travels along the sensory memory fiber and briefly floods that fiber at every point, the originally fixed node is faithfully doing its duty as a comparison device. By simple unitary logic, it recognizes the (umpteenth) reoccurrence of the signal of the same sensed feature with which it was originally fixed, or written as an engram.
