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 ...
Organizational memory: The construction of an instrument in accessible systemMemória organizacional: A construção de um instrumento em sistema acessível
(2020-08-01)
One of the fundamental assignments of archivists is the creation of means of recording and preserving the memory of organizations. Organizational memory, supported by records management and information management, is able ...
Hippocampal a7-nicotinic cholinergic receptors modulate memory reconsolidation: A potential strategy for recovery from amnesia
(Elsevier, 2013-11)
When subjects are exposed to new learning experiences, the novel information could be acquired and eventually stored through memory consolidation process. The exposure of mice to a novel experience (a hole-board) after ...

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, ...
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 ...
Corticosterone and propranolol's role on taste recognition memory
(Elsevier Inc, 2014-09)
Taste recognition is a robust procedure to study learning and memory processes, as well as the different stages involved in them, i.e. encoding, storage and recall. Considerable evidence indicates that adrenal hormones and ...
Calcineurin phosphatase as a negative regulator of fear memory in hippocampus: Control on nuclear factor-κB signaling in consolidation and reconsolidation
(Wiley, 2014-12)
Protein phosphatases are important regulators of neural plasticity and memory. Some studies support that the Ca2+/calmodulin-dependent phosphatase calcineurin (CaN) is, on the one hand, a negative regulator of memory ...
REVERSIBLE EFFECTS of ACUTE and LONG-TERM ADMINISTRATION of DELTA-9-TETRAHYDROCANNABINOL (THC) ON MEMORY in the RAT
(Elsevier B.V., 1991-08-01)
A study was designed to develop a measure of both acute and chronic effects of THC administration on memory in the rat. Errors in an 8-arm radial maze, before and after two delay intervals (5 s and 1 h, introduced between ...
