Reconsolidation or Extinction: Transcription Factor Switch in the Determination of Memory Course after Retrieval
(Society for Neuroscience, 2011-04)
In fear conditioning, aversive stimuli are readily associated with contextual features. A brief reexposure to the training context causes fear memory reconsolidation, whereas a prolonged reexposure induces memory extinction. ...
Spectral characteristics of the hippocampal LFP during contextual fear conditioningCaracterísticas espectrais da atividade elétrica hipocampal durante o medo condicionado ao contexto
(Instituto Israelita de Ensino e Pesquisa Albert Einstein, 2012)
OBJECTIVE: The hippocampus has an important role in the acquisition and recall of aversive memories. The objective of this study was to investigate the relationship among hippocampal rhythms. METHODS: Microeletrodes arrays ...
Efeito da morfina sobre a persistência da memória de medo condicionado contextual em ratos
(Universidade Federal de Santa MariaBrasilFarmacologiaUFSMPrograma de Pós-Graduação em FarmacologiaCentro de Ciências da Saúde, 2015-01-16)
It is established that opioids modulate brain networks involved in learning and memory. Studies using various learning tasks have shown that morphine impairs many forms of memory. A common feature of these studies is that ...
Lack of contextual-word predictability during reading in patients with mild Alzheimer disease
(Pergamon-Elsevier Science Ltd, 2014-06)
In the present work we analyzed the effect of contextual word predictability on the eye movement behavior of patients with mild Alzheimer disease (AD) compared to age matched controls, by using the eye tracking technique ...
Effects of pre- or post-training entorhinal cortex AP5 injection on fear conditioning
(Elsevier B.V., 2005-11-15)
Fear conditioning is one of the most studied paradigms to assess the neural basis of emotional memory. the circuitry involves NNMA receptor activation in the amygdala and, in the case of contextual conditioning, in the ...
Pre-test metyrapone impairs memory recall in fear conditioning tasks: lack of interaction with I--adrenergic activity
(Frontiers Research Foundation, 2015-03-03)
Cognitive processes, such as learning and memory, are essential for our adaptation to environmental changes and consequently for survival. Numerous studies indicate that hormones secreted during stressful situations, such ...
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 ...
Heterozygous Che-1 KO mice show deficiencies in object recognition memory persistence
(Elsevier Ireland, 2016-10)
Transcriptional regulation is a key process in the formation of long-term memories. Che-1 is a protein involved in the regulation of gene transcription that has recently been proved to bind the transcription factor NF-κB, ...
