Plasticity Requirements in IL-to-BLA Circuitry During Extinction Learning

, 2023
Distinguishing threatening situations from neutral ones is incredibly important for survival. In humans, failure to change perception of conditioned cues from threatening to irrelevant (colloquially called \u27extinction’) is thought to underlie PTSD and

The impact of the left inferior frontal gyrus on fear extinction: A transcranial direct current stimulation study

Brain Stimulation
Introduction: Fear extinction is a fundamental component of exposure-based therapies for anxiety-related disorders. The renewal of fear in a different context after extinction highlights the importance of contextual factors.

Investigating the Infralimbic-Amygdala Circuit During Fear Extinction Learning

, 2022
The Infralimbic (IL) cortex are thought to be involved in fear extinction learning yet the specific projection neurons and the mechanisms they use remain unknown.

Intermittent theta burst stimulation to the left prefrontal cortex enhances extinction learning but not extinction recall

Non-invasive brain stimulation targeting the left ventromedial prefrontal cortex (vmPFC) has shown potential in enhancing fear extinction. However, optimal stimulation parameters for clinical application remain unclear.

Predicting individual differences of fear and cognitive learning and extinction

Nature Communications
The ability to acquire new information and to modify previously learned knowledge are critical in an ever-changing world. However, the efficacy of learning is notably variable among individuals, with extinction learning being the epitome of such ...

The potential and pitfalls of de-extinction

, 2016
‘De-extinction’ is the nascent discipline that aims to one day literally revive now-extinct species from the dead. Although we have yet to see any successful attempts to truly resurrect an extinct species, several technologies are now in place that might

Learning to stop responding: The role of infralimbic cortex in punishment and extinction

, 2023
Learning to stop responding is a fundamental process in instrumental learning. An animal might learn to stop responding under a variety of conditions including extinction—in which a response is no longer reinforced—and punishment—in which a response ...

Forget the Stress: Retrograde Amnesia for Restraint Enhances Extinction Learning

, 2018
Stress has been found to influence learning in different ways. In particular, previous research has shown that stress enhances original learning but disrupts extinction learning.
