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 ...
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 ...
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 ...
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 ...
Efeito da valência do estímulo social na persistência da memória contextual
(Universidade Federal de Minas GeraisBrasilICB - INSTITUTO DE CIÊNCIAS BIOLOGICASPrograma de Pós-Graduação em Ciências Biológicas - Fisiologia e FarmacologiaUFMG, 2018-05-25)
The neurobiological bases of contextual memories come from paradigms involving negative stimuli, such as shock. However, memories of the same context can represent positive experiences, not just negative experiences. So, ...
Effects Of The Swimming Exercise On The Consolidation And Persistence Of Auditory And Contextual Fear Memory
(Elsevier Ireland LTDClare, 2016)
Reactivation-Dependent Amnesia for Contextual Fear Memories: Evidence for Publication Bias
(Society for Neuroscience, 2020-12)
Research on memory reconsolidation has been booming in the last two decades, with numerous high-impact publications reporting promising amnestic interventions in rodents and humans. However, our own recently-published ...
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 ...
Prior stress promotes the generalization of contextual fear memories: Involvement of the gabaergic signaling within the basolateral amygdala complex
(Pergamon-Elsevier Science Ltd, 2018-04)
Fear generalization occurs when a response, previously acquired with a threatening stimulus, is transferred to a similar one. However, it could be maladaptive when stimuli that do not represent a real threat are appraised ...
Contextual, but not auditory, fear conditioning is disrupted by neurotoxic selective lesion of the basal nucleus of amygdala in rats
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
The basolateral amygdala complex (BLA) is involved in acquisition of contextual and auditory fear conditioning. However, the BLA is not a single structure but comprises a group of nuclei, including the lateral (LA), basal ...
