Double Dissociation of Amygdala and Hippocampal Contributions to Trace and Delay Fear Conditioning [PDF]
PLoS ONE, 2011 A key finding in studies of the neurobiology of learning memory is that the amygdala is critically involved in Pavlovian fear conditioning. This is well established in delay-cued and contextual fear conditioning; however, surprisingly little is known of ...

Contextual fear conditioning leads to hypo-innervation of the left ventricular myocardium in female but not male C57BL/6J mice. [PDF]
IBRO Neurosci RepObjective: Contextual fear conditioning is an effective way of inducing and modelling anxiety-like states in rodents like mice. We examined the sex-dependent effects of contextual fear conditioning on the autonomic innervation of the left ventricular ...

Fear memory formation can affect a different memory: fear conditioning affects the extinction, but not retrieval, of conditioned taste aversion (CTA) memory [PDF]
Frontiers in Behavioral Neuroscience, 2014 The formation of fear memory to a specific stimulus leads to subsequent fearful response to that stimulus. However, it is not known whether the formation of fear memory can affect other memories.

Contextual and auditory fear conditioning continue to emerge during the periweaning period in rats. [PDF]
PLoS ONE, 2014 Anxiety disorders often emerge during childhood. Rodent models using classical fear conditioning have shown that different types of fear depend upon different neural structures and may emerge at different stages of development. For example, some work has

Frontiers in Cellular Neuroscience, 2023 IntroductionNew learning results in modulation of intrinsic plasticity in the underlying brain regions. Such changes in intrinsic plasticity can influence allocation and encoding of future memories such that new memories encoded during the period of ...

Scientific Reports, 2021 The balance between activities of fear neurons and extinction neurons in the basolateral nucleus of the basal amygdala (BAL) has been hypothesized to encode fear states after extinction.

Behavioral Expression of Contextual Fear in Male and Female Rats
Frontiers in Behavioral Neuroscience, 2021 The study of fear conditioning has led to a better understanding of fear and anxiety-based disorders such as post-traumatic stress disorder (PTSD). Despite the fact many of these disorders are more common in women than in men, the vast majority of work ...

Multiple factors contribute to flight behaviors during fear conditioning
Scientific Reports, 2023 Shifting defensive mode from one to another by the imminence of threat is crucial for survival. The transition of defensive mode from freezing to flight is observed during the modified fear conditioning, however, the flight during fear conditioning is ...

Reversible plasticity of fear memory-encoding amygdala synaptic circuits even after fear memory consolidation. [PDF]
PLoS ONE, 2011 It is generally believed that after memory consolidation, memory-encoding synaptic circuits are persistently modified and become less plastic. This, however, may hinder the remaining capacity of information storage in a given neural circuit.

Molecular Brain, 2019 Information from direct experience and observation of others is integrated in the brain to enable appropriate responses to environmental stimuli. Fear memory can be acquired by observing a conspecific’s distress.
