Perception and Memory
According to spreading activation theory, semantic memory is organized on the basis of semantic relatedness or semantic distance. Spreading activation spreads most strongly to other concepts that are closely related semantically, and more weekly to those that are more distant semantically. The spreading activation model has generally proved more successful than the hierarchical network model. (Baddeley, et.al.; Memory, 120)
Associative Nature of Memory
Neural pattern activations (Memory Trace Pattern, Engram) via the most efficacious synapses.
Neural activity patterns are ignited by fragmentary cues.
Extensive dendritic trees of projection neurons.
Interneurons connecting projection neurons dendritic trees provide tuning for sensory and top-down afferents.
