Agentes poliaminérgicos modulam a reconsolidação da memória de medo em ratos
(Universidade Federal de Santa MariaBRBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica Toxicológica, 2013-08-19)
The memory may be studied according with memory's phases, which is acquisition, consolidation and recall. Memories once consolidated, are no more susceptible to interventions, but when reactivated, some of these memories ...
Efeito da espermidina sobre a persistência da memória em ratos
(Universidade Federal de Santa MariaBRBioquímicaUFSMPrograma de Pós-Graduação em Ciências Biológicas: Bioquímica Toxicológica, 2013-02-22)
The long-term memory involves three stages: acquisition, consolidation and extinction. However was recently described a new phase of consolidation, called the persistence of memory. At this stage, crucial events occur 12 ...
The lateral neocortex is critical for contextual fear memory reconsolidation
(Nature Publishing Group, 2019-08)
Memories are a product of the concerted activity of many brain areas. Deregulation of consolidation and reprocessing of mnemonic traces that encode fearful experiences might result in fear-related psychopathologies. Here, ...
The effect of Midazolam and Propranolol on fear memory reconsolidation in ethanol-withdrawn rats: Influence of D-cycloserine
(Oxford University Press, 2014-01)
Background: Withdrawal from chronic ethanol facilitates the formation of contextual fear memory and delays the onset to extinction, with its retrieval promoting an increase in ethanol consumption. Consequently, manipulations ...
A comparison of behavioral and pharmacological interventions to attenuate reactivated fear memories
(Cold Spring Harbor Lab Press, 2017-08)
Two experiments using rats in a contextual fear memory preparation compared two approaches to reduce conditioned fear: (1) pharmacological reconsolidation blockade and (2) reactivation-plus-extinction training. In Experiment ...
On Disruption of Fear Memory by Reconsolidation Blockade: Evidence from Cannabidiol Treatment
(NATURE PUBLISHING GROUPLONDON, 2012)
The search for reconsolidation blockers may uncover clinically relevant drugs for disrupting memories of significant stressful life experiences, such as those underlying the posttraumatic stress disorder. Considering the ...
Hippocampal dendritic spines remodeling and fear memory are modulated by GABAergic signaling within the basolateral amygdala complex
(Wiley-liss, Div John Wiley & Sons Inc, 2015-05)
GABAergic signaling in the basolateral amygdala complex (BLA) plays a crucial role on the modulation of the stress influence on fear memory. Moreover, accumulating evidence suggests that the dorsal hippocampus (DH) is a ...
Effects Of The Swimming Exercise On The Consolidation And Persistence Of Auditory And Contextual Fear Memory
(Elsevier Ireland LTDClare, 2016)
Inactivation of the dorsolateral periaqueductal gray matter impairs the promoting influence of stress on fear memory during retrieval
(Springer Heidelberg, 2019-11)
Exposure to stressful conditions induces long-lasting neurobiological changes in selected brain areas, which could be associated with the emergence of negative emotional responses. Moreover, the interaction of a stressful ...
TRPC3 channels critically regulate hippocampal excitability and contextual fear memory
(Elsevier Science, 2015-03)
Memory formation requires de novo protein synthesis, and memory disorders may result from misregulated synthesis of critical proteins that remain largely unidentified. Plasma membrane ion channels and receptors are likely ...
