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 ...
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 ...
Academic and scientific memorial: formation, improvement and post-graduationMemorial acadêmico e científico: formação, aperfeiçoamento e pós-graduação
(Universidade Federal de Santa Maria, 2021)
A working memory intervention weakens the reconsolidation of a threat memory and its biases processing towards threat
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 ...
Repeating or spacing learning sessions are strategies for memory improvement with shared molecular and neuronal components
(Academic Press Inc Elsevier Science, 2020-07)
Intellectual disability is a common feature in genetic disorders with enhanced RAS-ERK1/2 signaling, including neurofibromatosis type 1 (NF1) and Noonan syndrome (NS). Additional training trials and additional spacing ...
Working memory training in children: A review of basic methodological criteria
(SAGE Publications, 2019-02)
Working memory is a process of great relevance during childhood due to its role in diverse complex skills. Like the rest of executive functions, it is highly sensitive to environmental influences, so it is assumed that it ...
Requirement of an early activation of BDNF/c-fos cascade in the retrosplenial cortex for the persistence of a long-lasting aversive memory
(Oxford University Press, 2015-12)
During the past few years, there has been growing interest in the role of the retrosplenial cortex (RSC) in memory processing. However, little is known about the molecular changes that take place in this brain region during ...
