Neural Mechanisms of Extinction Learning and Retrieval [PDF]

Neuropsychopharmacology, 2007
Emotional learning is necessary for individuals to survive and prosper. Once acquired, however, emotional associations are not always expressed. Indeed, the regulation of emotional expression under varying environmental conditions is essential for mental health. The simplest form of emotional regulation is extinction, in which conditioned responding to

The role of consciousness in threat extinction learning

Consciousness and Cognition, 2023
Extinction learning is regarded as a core mechanism underlying exposure therapy. The extent to which learned threats can be extinguished without conscious awareness is a controversial and on-going debate. We investigated whether implicit vs. explicit exposure to a threatened stimulus can modulate defence responses measured using pupillometry.

HDAC1-mediated regulation of GABA signaling within the lateral septum facilitates long-lasting social fear extinction in male mice

Translational Psychiatry, 2023
Social anxiety disorder (SAD) is caused by traumatic social experiences. It is characterized by intense fear and avoidance of social contexts, which can be robustly mimicked by the social fear conditioning (SFC) paradigm.

Examining Differences in Fear Learning in Patients With Obsessive-Compulsive Disorder With Pupillometry, Startle Electromyography and Skin Conductance Responses

Frontiers in Psychiatry, 2021
Obsessive-compulsive disorder (OCD) is characterized by recurrent, persistent thoughts and repetitive behaviors causing stress and anxiety. In the associative learning model of OCD, mechanisms of fear extinction are supposed to partly underlie symptom ...

Neural signals of vicarious extinction learning [PDF]

Social Cognitive and Affective Neuroscience, 2016
Social transmission of both threat and safety is ubiquitous, but little is known about the neural circuitry underlying vicarious safety learning. This is surprising given that these processes are critical to flexibly adapt to a changeable environment.

Treatment of fear memories: interactions between extinction and reconsolidation

Anais da Academia Brasileira de Ciências, 2011
Retrieval labilizes memory traces and these gates two protein synthesis-dependent processes in the brain: extinction, which inhibits further retrieval, and reconsolidation, which may enhance retrieval or change its content.
