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 ...
Post-weaning housing conditions influence freezing during contextual fear conditioning in adult rats
(Elsevier Science, 2018-11)
The present study aimed to investigate the influence of housing conditions on contextual fear memory malleability. Male Wistar rats were housed in enriched, standard, or impoverished conditions after weaning and remained ...
Involvement of the prelimbic cortex in contextual fear conditioning with temporal and spatial discontinuity
(Academic Press Inc Elsevier Science, 2017)
Time plays an important role in conditioning, it is not only possible to associate stimuli with events that overlap, as in delay fear conditioning, but it is also possible to associate stimuli that are discontinuous in ...
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 ...
Hippocampal structural plasticity accompanies the resulting contextual fear memory following stress and fear conditioning
(Cold Spring Harbor Lab Press, 2013-10)
The present research investigated the resulting contextual fear memory and structural plasticity changes in the dorsal hippocampus (DH) following stress and fear conditioning. This combination enhanced fear retention and ...
El efecto de la (im)predictabilidad en el miedo contextual: una réplica de hallazgos básicosThe effect of (un)predictability on contextual fear: A replication of the basic findings
(Pontificia Universidad Católica del Perú. Fondo EditorialPE, 2017)
Regulation of conditioned and unconditioned fear in rats by 5-HT1A receptors in the dorsal periaqueductal gray
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
Studies on the involvement of 5-HT1-mediated mechanisms in the dorsal periaqueductal gray (dPAG) of animals with past stressful experiences have not been conducted so far. We investigated the role of 5-HT1 receptors in the ...
What ethologically based models have taught us about the neural systems underlying fear and anxiety
(Associação Brasileira de Divulgação Científica, 2012)
Classical Pavlovian fear conditioning to painful stimuli has provided the generally accepted view of a core system centered in the central amygdala to organize fear responses. Ethologically based models using other sources ...
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 ...
The indirect amygdala-dorsal striatum pathway mediates conditioned freezing: Insights on emotional memory networks
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The dorsal striatum (DS) is involved in various forms of learning and memory such as procedural learning, habit learning, reward-association and emotional learning. We have previously reported that bilateral DS lesions ...
