The role of the medial prefrontal cortex in the conditioning and extinction of fear

TF Giustino, S Maren - Frontiers in behavioral neuroscience, 2015 - frontiersin.org
Once acquired, a fearful memory can persist for a lifetime. Although learned fear can be
extinguished, extinction memories are fragile. The resilience of fear memories to extinction …

Understanding the dynamic and destiny of memories

L de Oliveira Alvares, FH Do-Monte - Neuroscience & Biobehavioral …, 2021 - Elsevier
Memory formation enables the retention of life experiences overtime. Based on previously
acquired information, organisms can anticipate future events and adjust their behaviors to …

[HTML][HTML] How engram mediates learning, extinction, and relapse

H Lee, BK Kaang - Current Opinion in Neurobiology, 2023 - Elsevier
Fear learning ensures survival through an expression of certain behavior as a conditioned
fear response. Fear memory is processed and stored in a fear memory circuit, including the …

Impaired fear extinction in adolescent rodents: behavioural and neural analyses

KD Baker, MA Bisby, R Richardson - Neuroscience & Biobehavioral …, 2016 - Elsevier
Despite adolescence being a developmental window of vulnerability, up until very recently
there were surprisingly few studies on fear extinction during this period. Here we summarise …

Forming competing fear learning and extinction memories in adolescence makes fear difficult to inhibit

KD Baker, R Richardson - Learning & memory, 2015 - learnmem.cshlp.org
Fear inhibition is markedly impaired in adolescent rodents and humans. The present
experiments investigated whether this impairment is critically determined by the animal's …

[HTML][HTML] Implicit aversive memory under anaesthesia in animal models: a narrative review

N Samuel, AH Taub, R Paz, A Raz - British Journal of Anaesthesia, 2018 - Elsevier
Explicit memory after anaesthesia has gained considerable attention because of its negative
implications, while implicit memory, which is more elusive and lacks patients' explicit recall …

Effect of D‐cycloserine in conjunction with fear extinction training on extracellular signal‐regulated kinase activation in the medial prefrontal cortex and amygdala in rat

SC Gupta, BG Hillman, A Prakash… - European Journal of …, 2013 - Wiley Online Library
D‐cycloserine (DCS) is currently under clinical trials for a number of neuropsychiatric
conditions and has been found to augment fear extinction in rodents and exposure therapy …

[HTML][HTML] Inactivation of the medial prefrontal cortex interferes with the expression but not the acquisition of differential fear conditioning in rats

YK Lee, JS Choi - Experimental neurobiology, 2012 - ncbi.nlm.nih.gov
The medial prefrontal cortex (mPFC) has been implicated in the processing of emotionally
significant stimuli, particularly the inhibition of inappropriate responses. We examined the …

Reversible plasticity of fear memory-encoding amygdala synaptic circuits even after fear memory consolidation

I Hong, J Kim, J Lee, S Park, B Song, J Kim, B An… - PLoS …, 2011 - journals.plos.org
It is generally believed that after memory consolidation, memory-encoding synaptic circuits
are persistently modified and become less plastic. This, however, may hinder the remaining …

[HTML][HTML] Medial prefrontal cortex circuit function during retrieval and extinction of associative learning under anesthesia

GE Fenton, DM Halliday, R Mason, CW Stevenson - Neuroscience, 2014 - Elsevier
Associative learning is encoded under anesthesia and involves the medial prefrontal cortex
(mPFC). Neuronal activity in mPFC increases in response to a conditioned stimulus (CS+) …
