Memory built in conjunction with a stressor is privileged: Reconsolidation-resistant memories in the crab Neohelice
(Pergamon-Elsevier Science Ltd, 2020-04)
The dynamics of memory processes are conserved throughout evolution, a feature based on the hypothesis of a common origin of the high-order memory centers in bilateral animals. Reconsolidation is just one example. The ...
Ghrelin and memory: Differential effects on acquisition and retrieval
(Elsevier Science Inc, 2010-06)
In a previous paper we have demonstrated that the orexigenic peptide Ghrelin (Ghr), increases memory retention in rats and mice. In the present work we evaluated the Ghr effect when it was administered previous the training ...
Extinction and recovery of an avoidance memory impaired by scopolamine
(Pergamon-Elsevier Science Ltd, 2017-03)
Pre-training administration of scopolamine (SCP) resembles situations of cholinergic dysfunction, leading to memory impairment of mice trained in an inhibitory avoidance task. We suggest here that SCP does not impair memory ...
Enhancement of long-term memory expression by a single trial during consolidation
(Elsevier Ireland, 2011-01)
Before the memory trace is stored long term, it must undergo a phase of consolidation during which it remains susceptible to modifications. It has previously been proposed that during consolidation, memories are kept from ...
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 ...
Argentines’ collective memories of the military Junta of 1976: differences and similarities across generations and ideology
(Routledge, 2016-08)
Although memories about a nation's past usually are semantic in nature, a distinction needs to be made between lived and distant semantic collective memories. The former refers to memories of community-relevant events ...
Disruptive effect of midazolam on fear memory reconsolidation: Decisive influence of reactivation time span and memory age
(Nature Publishing Group, 2009-01)
Benzodiazepine (BDZ) administered shortly after retrieval disrupts the reconsolidation of fear memory. In this research, we explored the way in which different factors that limit the emergence of such process may affect ...
Positive and neutral updating reconsolidate aversive episodic memories via different routes
(Academic Press Inc Elsevier Science, 2021-01)
Aversive memories are long-lasting and prone to burden our emotional wellbeing and mental health. Yet, how to remedy the maladaptive effects of aversive memories remains elusive. Using memory reactivation and emotional ...
About Learning, Memory, and Neural Circuits: An Approaching to the Cognitive Processes in Living Systems
(American Scientific Publishers, 2010-06)
Learning can be considered a fundamental evolutionary advance to those living systems that acquired this capacity during the early evolution of life. Perception of an environment that has past and present permitted primitive ...
Updating contextual information during consolidation as result of a new memory trace
(Academic Press Inc Elsevier Science, 2010-05)
Reconsolidation studies have led to the hypothesis that memory, when labile, would be modified in order to incorporate new information. This view has reinstated original propositions suggesting that short-term memory ...
