Extinction Activates a Distinct Set of Neurons from the Fear Memory Cellular Traces. In addition to being a dynamic modification of fear memory ...

Retrieval induces reconsolidation of fear extinction memory - PMC

Here, we report that inhibition of protein synthesis in the CA1 region of the dorsal hippocampus after retrieval of fear extinction impedes subsequent ...

Memory retrieval, reconsolidation, and extinction - Frontiers

Memory updating with a single trial of delay conditioning following initial trace fear conditioning, which is dependent on cortical structures, resulted in ...

Memory Trace for Fear Extinction: Fragile yet Reinforceable

Based on the behavioral hypothesis that extinction is new learning and forms an extinction memory, this new memory is more readily forgettable than the original ...

Neural circuits for the adaptive regulation of fear and extinction ...

We have recently shown, for example, that the retrieval of a contextual fear memory reactivates dorsal hippocampal ensembles active during fear conditioning.

Mechanisms of fear extinction | Molecular Psychiatry - Nature

In humans, expression of extinction of conditioned fear is associated with increased BOLD response in the subgenual anterior cingulate (vmPFC) ...

attenuating remote fear memories by reconsolidation-updating

By capitalizing on an intrinsically relevant phase of memory, reconsolidation-updating harbors the potential to permanently alter remote fear ...

How engram mediates learning, extinction, and relapse

A gradual decrease in conditioned fear response can be induced by fear extinction, which is mediated through the weakening of the original fear memory traces ...

Amygdala Reward Neurons Form and Store Fear Extinction Memory

Here we demonstrate that a fear extinction memory engram is formed and stored in a genetically distinct basolateral amygdala (BLA) neuronal population that ...

Fear conditioning - Wikipedia

In the mouse, changed gene expression is also seen in the hippocampus at one hour and 24 hours after fear conditioning. These changes are transient in the ...

A Stable Sparse Fear Memory Trace in Human Amygdala

Pavlovian fear conditioning is highly conserved across species, providing a powerful model of aversive learning. In rodents, fear memory is ...

Enhancement of extinction memory by pharmacological and ...

Although temporarily effective, extinction does not erase an original fear association. Since the extinction trace tends to fade over time, the ...
