The impact of temporal distribution on fear extinction learning. [PDF]
Int J Clin Health PsycholFear extinction is the foundation of exposure therapy for anxiety and phobias. However, the stability of extinction memory diminishes over time, coinciding with fear recovery. To augment long-term extinction retention, the temporal distribution of extinction learning sessions is critical.

Extinction Learning in Humans [PDF]
Neuron, 2004 Understanding how fears are acquired is an important step in translating basic research to the treatment of fear-related disorders. However, understanding how learned fears are diminished may be even more valuable.

Extinction learning in mice [PDF]
, 2010 Anxiety disorders are characterized by an exaggerated fear response towards a non-harmful stimulus or situation. Exposure therapy is an effective treatment and consists of repeated non-reinforced exposures to the stimulus. Currently the index of beneficial learning is the decreased level of fear at the end of an exposure session.

Learning to learn in conditioning and extinction in humans
Behavioural Processes, 2018 Learning to Learn (LTL) is the transfer of learning, separate from stimulus generalization, that appears across tasks that share a similar structure. Three experiments examined this phenomenon in both conditioning and extinction learning in humans.

There Is More Than One Kind of Extinction Learning [PDF]
Frontiers in Systems Neuroscience, 2019 The view that different kinds of memory are mediated by dissociable neural systems has received extensive experimental support. Dissociations between memory systems are usually observed during initial acquisition, consolidation, and retrieval of memory ...

eLife, 2018 Extinction of fear responses is critical for adaptive behavior and deficits in this form of safety learning are hallmark of anxiety disorders. However, the neuronal mechanisms that initiate extinction learning are largely unknown.

Behavioral tagging of extinction learning [PDF]
International Journal of Psychophysiology, 2012 Extinction of contextual fear in rats is enhanced by exposure to a novel environment at 1–2 h before or 1 h after extinction training. This effect is antagonized by administration of protein synthesis inhibitors anisomycin and rapamycin into the hippocampus, but not into the amygdala, immediately after either novelty or extinction ...

Extinction Learning and Adult Neurogenesis [PDF]
Neuropsychopharmacology, 2010 Extinction of maladaptive conditioned responses or behaviors is a process of new and active learning, and requires the organism to learn new stimulus–response and action–outcome relationships, and to form new associations between previously hypersalient stimuli (ie, trauma-related cues and contexts) and appropriate cognitive and/or behavioral responses.

eLife, 2021 Trace conditioning and extinction learning depend on the hippocampus, but it remains unclear how neural activity in the hippocampus is modulated during these two different behavioral processes.

Differential activation of anatomically defined neuronal subpopulations in the amygdala during fear conditioning and extinction [PDF]
, 2009 The amygdala is a key structure of the neuronal circuitry mediating expression and extinction of conditioned fear. However, fear memories are thought to be encoded in a larger network comprising the medial prefrontal cortex (mPFC) and the ...
