Exposure to Violence and Neglect Images Differentially Influences Fear Learning and Extinction
, 2020 The mechanisms by which exposure to adversity contributes to psychopathology development are poorly understood. Recent models link experiences of threat of harm and deprivation to psychopathology via disruptions in learning mechanisms underlying fear ...

eLife, 2021 Learning to be safe is central for adaptive behaviour when threats are no longer present. Detecting the absence of an expected threat is key for threat extinction learning and an essential process for the behavioural treatment of anxiety-related ...

Extinction of cue-evoked drug-seeking relies on degrading hierarchical instrumental expectancies [PDF]
, 2014 There has long been need for a behavioural intervention that attenuates cue-evoked drug-seeking, but the optimal method remains obscure. To address this, we report three approaches to extinguish cue-evoked drug-seeking measured in a Pavlovian to ...

Functional and Dysfunctional Neuroplasticity in Learning to Cope with Stress
Brain Sciences, 2020 In this brief review, we present evidence of the primary role of learning-associated plasticity in the development of either adaptive or maladaptive coping strategies.

Modulation of the extinction of fear learning
Brain Research Bulletin, 2014 We review recent work on extinction learning with emphasis on its modulation. Extinction is the learned inhibition of responding to previously acquired tasks. Like other forms of learning, it can be modulated by a variety of neurotransmitter systems and behavioral procedures.

Concurrent extinction does not render appetitive conditioning context specific [PDF]
, 2011 In an experiment with rats, an appetitive conditioning method was used to investigate the generality of the hypothesis that extinction should arouse attention to contextual cues, resulting in all learning in that context becoming context specific.

Frontiers in Behavioral Neuroscience, 2018 Prolonged exposure (PE) is an empirically supported efficacious treatment for posttraumatic stress disorder (PTSD). In this focused review, we briefly review the neurobiological networks in PTSD relevant to PE, discuss the theoretical basis of PE, review

Theta coupling within the medial prefrontal cortex regulates fear extinction and renewal
iScience, 2022 Summary: Fear learning, and its extinction, are fundamental learning processes that allow for a response adaptation to aversive events and threats in the environment.

Cholinergic regulation of fear learning and extinction [PDF]
Journal of Neuroscience Research, 2016 Cholinergic activation regulates cognitive function, particularly long‐term memory consolidation. This Review presents an overview of the anatomical, neurochemical, and pharmacological evidence supporting the cholinergic regulation of Pavlovian contextual and cue‐conditioned fear learning and extinction.
