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 ...
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 ...
Introspection during short-term memory scanning
(2018)
The literature in metacognition has argued for many years that introspective access to our own mental content is restricted to the cognitive states associated with the response to a task, such as the level of confidence ...
Neural correlates of expression-independent memories in the crab Neohelice
(Academic Press Inc Elsevier Science, 2016-05)
The neural correlates of memory have been usually examined considering that memory retrieval and memory expression are interchangeable concepts. However, our studies in the crab Neohelice (Chasmagnathus) granulata and in ...
Retrieval under stress decreases the long-term expression of a human declarative memory via reconsolidation
(Elsevier, 2017-07)
Acute stress impairs memory retrieval of several types of memories. An increase in glucocorticoids, several minutes after stressful events, is described as essential to the impairing retrieval-effects of stressors. Moreover, ...
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 ...
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 ...
