Early β adrenoceptor dependent time window for fear memory persistence in APPswe/PS1dE9 mice

Scientific Reports, 2021
In this study we demonstrate that 2 month old APPswe/PS1dE9 mice, a transgenic model of Alzheimer’s disease, exhibited intact short-term memory in Pavlovian hippocampal—dependent contextual fear learning task. However, their long-term memory was impaired.

Working memory and fear conditioning [PDF]

Proceedings of the National Academy of Sciences, 2003
Previous studies of associative learning implicate higher-level cognitive processes in some forms of classical conditioning. An ongoing debate is concerned with the extent to which attention and awareness are necessary for trace but not delay eye-blink conditioning [Clark, R. E. & Squire, L. R.

Evaluating an internet-delivered fear conditioning and extinction protocol using response times and affective ratings

Scientific Reports, 2022
Pavlovian fear conditioning is widely used to study mechanisms of fear learning, but high-throughput studies are hampered by the labor-intensive nature of examining participants in the lab.

Adolescent Alcohol Exposure Results in Sex-specific Alterations in Conditioned Fear Learning and Memory in Adulthood

Frontiers in Pharmacology, 2022
The present study used auditory fear conditioning to assess the impact of repeated binge-like episodes of alcohol exposure during adolescence on conditioned fear in adulthood.

Role of p38 MAPK inhibitor in conditioned fear [PDF]

, 2015
p38 mitogen activated protein kinase (p38) is a kinase that has been implicated in cellular plasticity, stress, and psychiatric disorders and recently in the process of DNA repair.

Conditioned fear modulates visual selection. [PDF]

Emotion, 2013
Eye movements reflect the dynamic interplay between top-down- and bottom-up-driven processes. For example, when we voluntarily move our eyes across the visual field, salient visual stimuli in the environment may capture our attention, our eyes, or modulate the trajectory of an eye movement. Previous research has shown that the behavioral relevance of a

Auditory fear memory retrieval requires BLA-LS and LS-VMH circuitries via GABAergic and dopaminergic neurons

EMBO Reports
Fear and associated learning and memory are critical for developing defensive behavior. Excessive fear and anxiety are important components of post-traumatic stress disorder.

Plasticity of fear and safety neurons of the amygdala in response to fear extinction

Frontiers in Behavioral Neuroscience, 2015
Fear inhibition learning induces plasticity and remodeling of circuits within the amygdala. Most studies examine these changes in nondiscriminative fear conditioning paradigms.

Don't fear 'fear conditioning'

Neuroscience and Biobehavioral Reviews, 2017
The so-called 'replicability crisis' has sparked methodological discussions in many areas of science in general, and in psychology in particular. This has led to recent endeavours to promote the transparency, rigour, and ultimately, replicability of research.

Pharmacological depletion of serotonin in the basolateral amygdala complex reduces anxiety and disrupts fear conditioning [PDF]

, 2015
The basolateral and lateral amygdala nuclei complex (BLC) is implicated in a number of emotional responses including conditioned fear and social anxiety.
