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 ...
Preventing Return of Fear in an Animal Model of Anxiety: Additive Effects of Massive Extinction and Extinction in Multiple Contexts
(Behavior Therapy 44 (2013) 249–261, 2013)
Fear conditioning and experimental extinction have been
presented as models of anxiety disorders and exposure
therapy, respectively. Moreover, the return of fear serves as
a model of relapse after exposure therapy. Here ...

Classical tone-shock conditioning induces Zenk expression in the pigeon (Columba livia) hippocampus

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 ...
Behavioral techniques for attenuating the expression of fear associations in an animal model of anxiety
(Elsevier, 2014)
Background and objectives: Recent data indicate that extinguished fear often returns when the testing
conditions differ from those of treatment. Several manipulations including extensive extinction training,
extinction ...
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 ...
Effects of reversible inactivation of the dorsal hippocampus on the behavioral and cardiovascular responses to an aversive conditioned context
(LIPPINCOTT WILLIAMS & WILKINS, 2008)
In rats, conditioned fear to context causes freezing immobility and cardiovascular changes. The dorsal hippocampus (DH) has a critical role in several memory processes, including conditioning fear to contextual information. ...
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 ...
