Strengthening a consolidated memory: The key role of the reconsolidation process
(Elsevier, 2014-09)
The reconsolidation hypothesis posits that the presentation of a specific cue, previously associated with a life event, makes the stored memory pass from a stable to a reactivated state. In this state, memory is again ...
Memory consolidation and reconsolidation in an invertebrate model: The role of the GABAergic system
(Pergamon-Elsevier Science Ltd, 2009-01)
Consolidation theory assumes that memories are labile during a limited time window after acquisition, but as time passes, memories become stable and resistant to amnesic agents. However, the vision of immutable memories ...
Repeated labilization-reconsolidation processes strengthen declarative memory in humans
(Public Library of Science, 2011-08)
The idea that memories are immutable after consolidation has been challenged. Several reports have shown that after the presentation of a specific reminder, reactivated old memories become labile and again susceptible to ...
Differential neurophysiological correlates of retrieval of consolidated and reconsolidated memories in humans: An ERP and pupillometry study
(Academic Press Inc Elsevier Science, 2020-10)
Consolidated memories can return to a labile state if they are reactivated by unpredictable reminders. To persist, active memories must be re-stabilized through a process known as reconsolidation. Although there is consistent ...
An appetitive experience after fear memory destabilization attenuates fear retention: Involvement GluN2B-NMDA receptors in the basolateral amygdala complex
(Cold Spring Harbor Laboratory Press, 2016-09)
It is known that a consolidated memory can return to a labile state and become transiently malleable following reactivation. This instability is followed by a restabilization phase termed reconsolidation. In this work, we ...
Chitosan from Marine Crustaceans: Production, Characterization and Applications
(IntechOpen, 2017)
Chitosan is a very useful marine polysaccharide that forms structural components in the exoskeleton of crustaceans. In this chapter, the production of chitosan (CH) and chitosan reticulated micro/nanoparticles (CHM) is ...
Positive emotional induction interferes with the reconsolidation of negative autobiographical memories, in women only
(Academic Press Inc Elsevier Science, 2018-11)
After reactivation, a previously consolidated memory can enter into a labile state followed by a re-stabilization process defined as reconsolidation. The aim of this study was to explore whether an existing negative ...
A working memory intervention weakens the reconsolidation of a threat memory and its biases processing towards threat
(Biorxiv, 2020-01)
BACKGROUND Threat-conditioning (TC) memory plays a central role in anxiety disorders, but not in a simple way. This memory impacts on complex cognitive systems by modifying behavioral responses with a bias to fearful stimuli ...
Behavioral tagging underlies memory reconsolidation
(National Academy of Sciences, 2020-07)
Memory reconsolidation occurs when a retrieving event destabilizes transiently a consolidated memory, triggering thereby a new process of restabilization that ensures memory persistence. Although this phenomenon has received ...
Estudo do envolvimento do córtex perirrinal na reconsolidação da memória de reconhecimento de objetos
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM NEUROCIÊNCIAS, 2019-03-14)
Consolidated memories can become labile when reactivated and, to persist, must
undergo a protein synthesis-dependent restabilization process called
reconsolidation. The perirhinal cortex (PER) regulates the flow of ...
