Are fear memories erasable? –reconsolidation of learned fear with fear relevant and fear-irrelevant stimuli [PDF]

open access: yesFrontiers in Behavioral Neuroscience, 2012
Recent advances in the field of fear learning have demonstrated that a single reminder exposure prior to extinction training can prevent the return of extinguished fear by disrupting the process of reconsolidation. These findings have however proven hard

Paraventricular thalamus hyperactivity mediates stress-induced sensitization of unlearned fear but not stress-enhanced fear learning (SEFL) [PDF]

open access: yeseLife
Exposure to stress can cause long-lasting enhancement of fear and other defensive responses that extend beyond the cues or contexts associated with the original traumatic event.

Observational Fear Learning in Rats: Role of Trait Anxiety and Ultrasonic Vocalization

open access: yesBrain Sciences, 2021
Rats can acquire fear by observing conspecifics that express fear in the presence of conditioned fear stimuli. This process is called observational fear learning and is based on the social transmission of the demonstrator rat’s emotion and the induction ...

A prospective study of pre-trauma fear learning and extinction as risk factors for posttraumatic stress disorder [PDF]

open access: yesJournal of Mood and Anxiety Disorders
Identifying risk for developing trauma-related disorders is a critical step in future prevention and intervention strategies. Impairments in inhibition of learned fear, such as safety signal learning and fear extinction, are suggested to be core ...

Dopamine prediction error signaling in a unique nigrostriatal circuit is critical for associative fear learning [PDF]

open access: yesNature Communications
Learning by experience that certain cues in the environment predict danger is crucial for survival. How dopamine (DA) circuits drive this form of associative learning is not fully understood.

Cerebellar control of fear learning via the cerebellar nuclei–Multiple pathways, multiple mechanisms?

open access: yesFrontiers in Systems Neuroscience, 2023
Fear learning is mediated by a large network of brain structures and the understanding of their roles and interactions is constantly progressing. There is a multitude of anatomical and behavioral evidence on the interconnection of the cerebellar nuclei ...

Bimodal modulation of L1 interneuron activity in anterior cingulate cortex during fear conditioning

open access: yesFrontiers in Neural Circuits, 2023
The anterior cingulate cortex (ACC) plays a crucial role in encoding, consolidating and retrieving memories related to emotionally salient experiences, such as aversive and rewarding events. Various studies have highlighted its importance for fear memory

Social learning about dangerous people by wild jackdaws [PDF]

open access: yesRoyal Society Open Science, 2019
For animals that live alongside humans, people can present both an opportunity and a threat. Previous studies have shown that several species can learn to discriminate between individual people and assess risk based on prior experience.

Hippocampal CCR5/RANTES Elevations in a Rodent Model of Post-Traumatic Stress Disorder: Maraviroc (a CCR5 Antagonist) Increases Corticosterone Levels and Enhances Fear Memory Consolidation

open access: yesBiomolecules, 2020
Background: Contextual fear conditioning (CFC) is a rodent model that induces a high and long-lasting level of conditioning associated with traumatic memory formation; this behavioral paradigm resembles many characteristics of posttraumatic stress ...
