Role Played by the Passage of Time in Reversal Learning

open access: yesFrontiers in Behavioral Neuroscience, 2018
Reversal learning is thought to involve an extinction-like process that inhibits the expression of the initial learning. However, behavioral evidence for this inhibition remains difficult to interpret as various procedures have been employed to study ...

Evidence for retarded extinction of aversive learning in anxious children

open access: yes, 2006
The habituation to intense acoustic stimuli and the acquisition of differentially conditioned fear were assessed in 53 clinically anxious and 30 non-anxious control children and young adolescents.

Functional Compartmentalization of the Contribution of Hippocampal Subfields to Context-Dependent Extinction Learning

open access: yesFrontiers in Behavioral Neuroscience, 2019
During extinction learning (EL), an individual learns that a previously learned behavior no longer fulfills its original purpose, or is no longer relevant.

The effects of spaced versus massed extinction training on extinction retention of conditioned fear learning in male rats

open access: yesFrontiers in Behavioral Neuroscience
IntroductionExtinction learning of conditioned fear behavior has been used as a translational model to study human fear-, anxiety-, trauma-, and stressor-related disorders and their underlying neurobiology in animal models because the underlying neural ...

Effects of 3,4-Methylenedioxymethamphetamine on Conditioned Fear Extinction and Retention in a Crossover Study in Healthy Subjects

open access: yesFrontiers in Pharmacology, 2022
Background: 3,4-Methylenedioxymethamphetamine (MDMA) has shown initial promise as an adjunct in psychotherapy to treat posttraumatic stress disorder (PTSD). Its efficacy and safety have been demonstrated across phase I–III studies. However, the mechanism

Cellular and oscillatory substrates of fear extinction learning [PDF]

open access: yesNature Neuroscience, 2017
The mammalian brain contains dedicated circuits for both the learned expression and suppression of fear. These circuits require precise coordination to facilitate the appropriate expression of fear behavior, but the mechanisms underlying this coordination remain unclear.

Blocking NMDA-receptors in the pigeon’s ‘prefrontal’ caudal nidopallium impairs appetitive extinction learning in a sign-tracking paradigm

open access: yesFrontiers in Behavioral Neuroscience, 2015
Extinction learning provides the ability to flexibly adapt to new contingencies by learning to inhibit previously acquired associations in a context-dependent manner. The neural networks underlying extinction learning were mostly studied in rodents using

The DA antagonist tiapride impairs context-related extinction learning in a novel context without affecting renewal

open access: yesFrontiers in Behavioral Neuroscience, 2015
Renewal describes the recovery of an extinguished response if recall is tested in a context different from the extinction context. Behavioral studies demonstrated that attention to relevant context strengthens renewal.

No effect of partial reinforcement on fear extinction learning and memory in C57BL/6J mice. [PDF]

open access: yesLearn Mem
Partial reinforcement schedules, wherein a conditioned stimulus (CS) is intermittently paired with an unconditioned stimulus (US) during associative learning, have been widely studied and found to affect the extinction and recall of learned behaviors ...

THE MEMORY SYSTEM ENGAGED DURING ACQUISITION DETERMINES THE EFFECTIVENESS OF DIFFERENT EXTINCTION PROTOCOLS

open access: yesFrontiers in Behavioral Neuroscience, 2015
Previous research indicates that extinction of rodent maze behavior may occur without explicit performance of the previously required response. In latent extinction, confining an animal to a previously rewarded goal location without reinforcement is ...
