As noted earlier the hippocampal region supports implicit learning and memory in certain situations, e.g. initial novelty processing, the learning and later recall of confusing cues, and implicit cognitive demands needing relational processing. Furthermore a functionally viable hippocampus seems to be needed to declaratively transform implicit fear conditioning memory explicit making it later recallable and retrievable. This process is noted below. It is a modification of Squire (2004). It depicts emotional conditioning’s place in implicit learning and memory. When fear conditioning is not linked with hippocampal processes, this memory’s post-training ability for declarative recall is impaired. As indicated earlier hippocampal linkage and viability modulates conditioning memory to make it declarative and retrievable.
