Neuronal signalling of fear memory [PDF]

Nature Reviews Neuroscience, 2004
The learning and remembering of fearful events depends on the integrity of the amygdala, but how are fear memories represented in the activity of amygdala neurons? Here, we review recent electrophysiological studies indicating that neurons in the lateral amygdala encode aversive memories during the acquisition and extinction of Pavlovian fear ...

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.

Pavlovian Olfactory Fear Conditioning: Its Neural Circuity and Importance for Understanding Clinical Fear-Based Disorders

Frontiers in Molecular Neuroscience, 2019
Odors have proven to be the most resilient trigger for memories of high emotional saliency. Fear associated olfactory memories pose a detrimental threat of potentially transforming into severe mental illness such as fear and anxiety-related disorders ...

Fear Memory [PDF]

Physiological Reviews, 2016
Fear memory is the best-studied form of memory. It was thoroughly investigated in the past 60 years mostly using two classical conditioning procedures (contextual fear conditioning and fear conditioning to a tone) and one instrumental procedure (one-trial inhibitory avoidance).

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.

Characterization of Fear Memory Reconsolidation [PDF]

The Journal of Neuroscience, 2004
Reactivation of consolidated memories returns them to a protein synthesis-dependent state. One interpretation of these findings is that the memory reconsolidates after use. Two alternative interpretations are that protein synthesis inhibition facilitates extinction and that postreactivation protein synthesis inhibition leads to an inability to retrieve

Post-acquisition CO2 Inhalation Enhances Fear Memory and Depends on ASIC1A

Frontiers in Behavioral Neuroscience, 2021
A growing body of evidence suggests that memories of fearful events may be altered after initial acquisition or learning. Although much of this work has been done in rodents using Pavlovian fear conditioning, it may have important implications for fear ...

The Small World of a Fear Memory [PDF]

Neuron, 2017
How are fear memories organized? In this issue of Neuron, Vetere et al. (2017) take a network-based approach to demonstrate the importance of highly interconnected hub regions in the consolidation of a fear memory. By doing so, they provide an elegant framework for predicting behavior from functional network properties.

Inhibitory circuits in fear memory and fear-related disorders

Frontiers in Neural Circuits, 2023
Fear learning and memory rely on dynamic interactions between the excitatory and inhibitory neuronal populations that make up the prefrontal cortical, amygdala, and hippocampal circuits. Whereas inhibition of excitatory principal cells (PCs) by GABAergic neurons restrains their excitation, inhibition of GABAergic neurons promotes the excitation of PCs ...
