A single standard for memory: the case for reconsolidation

It is established that the same operational definitions and types of evidence underpin the deduction of both reconsolidation and consolidation, thus validating the extrapolation that post-retrieval memory plasticity reflects processes akin to those that stabilized the memory following acquisition.

Reconsolidation: maintaining memory relevance

University of Birmingham Reconsolidation: maintaining memory relevance

The adaptive function of memory reconsolidation is explored in more detail, with a strong emphasis on its role in updating memories to maintain their relevance.

Reconsolidation of memory: A decade of debate

Episodic memory: reconsolidation

It is shown that reminders can open a previously established memory to updating based on new experience, and that under laboratory conditions the experimental context plays a critical role in determining whether or not such memory updating will occur.

Reconsolidation and the fate of consolidated memories

The consolidation-reconsolidation debate is addressed and some controversial issues about the reconsolidation hypothesis are discussed, in particular the biological role of this process.

Repeated Labilization-Reconsolidation Processes Strengthen Declarative Memory in Humans

This work proposes central concepts for the reconsolidation process, emphasizing its biological role and the parametrical constrains for this function to be operative.

Memory Reconsolidation and Extinction Have Distinct Temporal and Biochemical Signatures

The temporal dynamics of memory reconsolidation are dependent on the strength and age of the memory, such that younger and weaker memories are more easily reconsolidated than older and stronger memories.

Stability of Retrieved Memory: Inverse Correlation with Trace Dominance

It is reported that in both conditioned taste aversion in the rat and fear conditioning in the medaka fish, the stability of retrieved memory is inversely correlated with the control of behavior by that memory.

A heated debate has been revitalized on whether memories become labile and must undergo some form of renewed consolidation every time they are activated, and on fundamental issues concerning the nature of the memory trace, its maturation, persistence, retrievability, and modifiability.

Characterization of Fear Memory Reconsolidation

It is reported that reconsolidation cannot be reduced down to facilitated extinction and application of reminder shock does not result in the reinstatement of the memory, supporting the idea that reactivation of consolidated memories initiates a second time-dependent memory formation process.

Independent Cellular Processes for Hippocampal Memory Consolidation and Reconsolidation

By infusing antisense oligodeoxynucleotides into the hippocampus of rats, this work shows that consolidation and reconsolidation are doubly dissociable component processes of memory.

Linking New Information to a Reactivated Memory Requires Consolidation and Not Reconsolidation Mechanisms

It is found that reconsolidation does not contribute to the formation of an association between new and reactivated information, and instead, it recruits mechanisms similar to those underlying consolidation of a new memory.

Reconsolidation of fresh, remote, and extinguished fear memory in medaka: old fears don't die

It is shown that reconsolidation occurs in fresh long‐term memories but not in remote memories, and that the apparent amnesia induced by blockade of reconsolidations can be reinstated by an unpaired reinforcer, a procedure that has no effect on amnesia inducing by blockade.
