This contrasts with our current findings, in which the hippocampus showed less univariate activity for relational versus item attention.

WebbThus, our results may suggest that OUA probably improves the new information or non-traumatic memory consolidation in the hippocampus, replacing the previous fear memory. However, more studies are necessary to elucidate the OUA mechanism, which is the mechanism that is triggered by CUS that leads to the increased fear extinction in …

Webb9 aug. 2006 · Classic studies of amnesia led to characterizations of hippocampal function emphasizing involvement in long-term memory rather than short-term (or working) memory.
