Definition of different memory types

UCS and NS input stimuli are schematized as switches, whereas response R is schematized as ON/OFF electric bulb. To represent the ON, OFF, Repeated, and Relaxed states of UCS and NS, blue and green switches with different positions are used, respectively. We define the pre-requisites for memory testing in the block headed as Before training. It requires that initially (at time t_0) UCS, NS, and R should be OFF, and such that UCS triggers R and NS does not trigger R. The memory evaluation table describes each memory type as a row. The five broad memory types are described here as UCS Based, Pairing, Transfer, Associative, and Consolidation memory. For each memory evaluation, there are training and testing phases, showing the overall dynamic and what is learned (the stable change in system behavior) over time.
