Dissociated roles of dorsal and ventral hippocampus in recall and extinction of conditioned fear in male and female juvenile rats

CHJ Park, DE Ganella, CJ Perry, JH Kim - Experimental Neurology, 2020 - Elsevier
Reduction of conditioned fear expression by extinction underlies cue exposure therapies
that treat anxiety disorders. Extinction is context-specific. Renewal, for example, is the …

Hippocampal inactivation disrupts the acquisition and contextual encoding of fear extinction

KA Corcoran, TJ Desmond, KA Frey… - Journal of …, 2005 - Soc Neuroscience
In recent studies, inactivation of the dorsal hippocampus before the retrieval of extinguished
fear memories disrupted the context-dependent expression of these memories. In the …

Fear extinction in rodents: basic insight to clinical promise

M Barad - Current opinion in neurobiology, 2005 - Elsevier
Fear extinction, the reduction of fear by repeated exposure to the object of fear, is a crucial
paradigm of inhibitory learning and the acknowledged preclinical model for behavior …

Fear extinction in rats: implications for human brain imaging and anxiety disorders

MR Milad, SL Rauch, RK Pitman, GJ Quirk - Biological psychology, 2006 - Elsevier
Fear extinction is the decrease in conditioned fear responses that normally occurs when a
conditioned stimulus (CS) is repeatedly presented in the absence of the aversive …

Role of hippocampal β-adrenergic and glucocorticoid receptors in the novelty-induced enhancement of fear extinction

JF Liu, C Yang, JH Deng, W Yan, HM Wang… - Journal of …, 2015 - Soc Neuroscience
Fear extinction forms a new memory but does not erase the original fear memory. Exposure
to novelty facilitates transfer of short-term extinction memory to long-lasting memory …

Absence of fear renewal and functional connections between prefrontal cortex and hippocampus in infant mice

L Li, X Gao, Q Zhou - Neurobiology of Learning and Memory, 2018 - Elsevier
Impairment in fear extinction is widely viewed as a major contributor to, or even an
underlying mechanism of, the pathogenesis of anxiety disorders and PTSD. Children with …

Resistance to extinction is associated with impaired immediate early gene induction in medial prefrontal cortex and amygdala

C Herry, N Mons - European Journal of Neuroscience, 2004 - Wiley Online Library
Extinction of classical fear conditioning is thought to involve activity‐dependent potentiation
of synaptic transmission in the medial prefrontal cortex (mPFC), resulting in the inhibition of …

Erasing fear memories with extinction training

GJ Quirk, D Paré, R Richardson, C Herry… - Journal of …, 2010 - Soc Neuroscience
Decades of behavioral studies have confirmed that extinction does not erase classically
conditioned fear memories. For this reason, research efforts have focused on the …

Hippocampal inactivation disrupts contextual retrieval of fear memory after extinction

KA Corcoran, S Maren - Journal of Neuroscience, 2001 - Soc Neuroscience
Recent studies implicate the hippocampus in contextual memory retrieval. The present
experiments explore this possibility by examining the impact of reversible inactivation of the …

Recalling safety: cooperative functions of the ventromedial prefrontal cortex and the hippocampus in extinction

KA Corcoran, GJ Quirk - CNS spectrums, 2007 - cambridge.org
Anxiety disorders are commonly treated with exposure-based therapies that rely on
extinction of conditioned fear. Persistent fear and anxiety following exposure therapy could …
