TLDR
Rats showed retrogarde amnesia when electroconvulsive shock was administered 24 h after a fear conditioning trial when the shock was preceded by some of the specific conditioning cues but not others, suggesting that ECS can act to produce retrograde amnesia by means other than disrupting memory consolidation.Abstract:
Rats showed retrogarde amnesia when electroconvulsive shock was administered 24 h after a fear conditioning trial when the shock was preceded by some of the specific conditioning cues but not others. This result replicates the findings of Misanin, Miller, & Lewis (1968) and suggests that ECS can act to produce retrograde amnesia by means other than disrupting memory consolidation.read more

A single standard for memory: the case for reconsolidation.
Karim Nader,Oliver Hardt +1 more
TL;DR: 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.
Journal ArticleDOI
Memory traces unbound
TL;DR: The hypothesis that reactivation of a consolidated memory can return it to a labile, sensitive state - in which it can be modified, strengthened, changed or even erased is revisited.
Journal ArticleDOI
Mechanisms of memory stabilization: are consolidation and reconsolidation similar or distinct processes?
TL;DR: A working model is concluded that could explain the apparent controversy of memory vulnerability after reactivation and indicates brain areas involved in consolidation after initial training are not required for reconsolidation.

Hippocampal-Neocortical Interactions in Memory Formation, Consolidation, and Reconsolidation
TL;DR: This review, focusing on work using animals, updates a theoretical approach whose aim is to translate neuropsychological ideas about the psychological and anatomical organization of memory into the neurobiological domain and suggests that episodic-like memory consists of both automatic and controlled components.

A requirement for the immediate early gene zif268 in reconsolidation of recognition memory after retrieval.
TL;DR: It is shown that when a consolidated memory for objects is recalled, zif268 mutant mice are impaired in further long-term but not short-term recognition memory, indicating that IEG-mediated transcriptional regulation in neurons is one common molecular mechanism for the storage of newly formed and reactivated recognition memories.

Time-dependent processes in memory storage
TL;DR: The findings indicate that the long-lasting trace of an experience is not completely fixed, consolidated, or coded at the time of the experience, and that any search for the engram or the basis of memory is not going to be successful.

Retrograde Amnesia Produced by Electroconvulsive Shock after Reactivation of a Consolidated Memory Trace
TL;DR: Rats had a memory loss of a fear response when they received an electroconvulsive shock 24 hours after the fear-conditioning trial and preceded by a brief presentation of the conditioned stimulus, which throws doubt on the assertion that electro Convulsive shock exerts a selective amnesic effect on recently acquired memories.

TL;DR: This first of a series of symposia commemorating G. Stanley Hall’s contribution to psychology is devoted to the topic of memory, where an analysis of memory processes seems appropriate as a beginning.

Electroconvulsive shock effects on a reactivated memory trace: further examination.
TL;DR: Rats showed amnesia for conditioned fear training if given an electroconvulsive shock immediately after training, but retention was unimpaired when the electro Convulsive shock treatment was given 1 day after training.
