Contextual change after fear acquisition affects conditioned responding and the time course of extinction learning – Implications for renewal research

Frontiers in Behavioral Neuroscience, 2015
Context plays a central role in retrieving (fear) memories. Accordingly, context manipulations are inherent to most return of fear (ROF) paradigms (in particular renewal), involving contextual changes after fear extinction.

Maternal Experience Does Not Predict Fear Extinction and Anxiety-Like Behaviour in Primiparous Rats Post-weaning

Frontiers in Global Women's Health, 2021
Reproductive experience leads to long-lasting changes in anxiety-like behaviour and fear extinction, the laboratory model of exposure therapy for anxiety disorders.

Extinction of negative conditioned stimulus valence in human fear conditioning [PDF]

Fear conditioning is a common experimental paradigm for modelling the development, and exposure-based treatment, of anxiety disorders. Measures of fear such as threat-expectancy, physiological arousal, and fear ratings typically extinguish, however ...

Acute early-life stress results in premature emergence of adult-like fear retention and extinction relapse in infant rats [PDF]

, 2013
Recent studies have shown that chronic early life stress results in precocious expression of the adult-like phenotype of fear retention and inhibition. However, it is unknown whether the experience of acute early trauma has the same effects as exposure ...

Regulation of Fear Extinction in the Basolateral Amygdala by Dopamine D2 Receptors Accompanied by Altered GluR1, GluR1-Ser845 and NR2B Levels

Frontiers in Behavioral Neuroscience, 2017
The amygdala, a critical structure for both Pavlovian fear conditioning and fear extinction, receives sparse but comprehensive dopamine innervation and contains dopamine D1 and D2 receptors.

Longitudinal recordings of single units in the basal amygdala during fear conditioning and extinction

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.

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

Utilizing rewards to dampen fear and its recovery

Scientific Reports
Fearful memories can be extinguished by repeated exposure, without aversive outcomes. Fear extinction as the basis for exposure therapy, is a common treatment for anxiety and fear-related disorders, but it can be unpleasant and does not always work.

Novel approaches for strengthening human fear extinction: The roles of novelty, additional USs, and additional GSs [PDF]

, 2020
Since Watson and Rayner's (1920) initial demonstration that human fear can be learned by means of Pavlovian conditioning, neuroscientific and behavioral studies have provided a thorough understanding of fear acquisition. Less is known about the manner in

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...
