Fear arousal, initiated by an environmental threat, leads to activation of the stress response, a state of alarm that promotes an array of autonomic and endocrine changes designed to aid self-preservation. The stress response includes the release of glucocorticoids from the adrenal cortex and catecholamines from the adrenal medulla and sympathetic nerves. These stress hormones, in turn, provide feedback to the brain and influence neural structures that control emotion and cognition. To… 
Modulation of Fear Extinction by Stress, Stress Hormones and Estradiol: A Review
TLDR
Current animal and human data on the role of estradiol are summarized and possible interactions with stress or stress-response mediators in extinction are explored, aimed at identifying time-windows of enhanced (or reduced) sensitivity for fear extinction, and thus also for successful exposure therapy.
The influence of acute stress on the regulation of conditioned fear
TLDR
Research investigating the effects of acute stress and stress hormones on fear regulation in humans reveals that acute stress may impair the persistent inhibition of fear, presumably by altering prefrontal cortex function.
Stress-induced cognitive dysfunction: hormone-neurotransmitter interactions in the prefrontal cortex
TLDR
This review will focus on factors that influence the function of the prefrontal cortex, a brain region that governs higher-level cognitive processes and executive function that becomes markedly impaired by stress, producing measurable deficits in working memory.
Regulation of Excitatory Synapses and Fearful Memories by Stress Hormones
TLDR
How glucocorticoids and norepinephrine regulate the formation of fearful memories in rodents and humans and how these hormones can facilitate the storage of information by regulating excitatory synapses is reviewed.
A ghrelin-growth hormone axis drives stress-induced vulnerability to enhanced fear
TLDR
It is shown that stress-related increases in circulating ghrelin, a peptide hormone, are necessary and sufficient for stress-associated vulnerability to exacerbated fear learning and these actions of gh Relin occur in the amygdala, independent of the classic HPA stress axis.
Protect and harm: Effects of stress on the amygdala
Abstract The amygdala plays a key role in a range of adaptive social and emotional behaviors. As might be expected for a region that facilitates rapid changes, the amygdala is highly sensitive to the
The Neurobiology of Stress
Stressors represent a potential threat to the individual human or animal, and the stress response is integral to adapting to the stressor. The identification of a stimulus or collection of stimuli as
Cannabinoids and traumatic stress modulation of contextual fear extinction and GR expression in the amygdala-hippocampal-prefrontal circuit
TLDR
The findings suggest that the interaction between the cannabinoid and glucocorticoid systems is crucial in the modulation of emotional trauma.
Dopamine D2-like receptors modulate freezing response, but not the activation of HPA axis, during the expression of conditioned fear
TLDR
It is shown that corticosterone, acting through mineralocorticoid receptors in the ventral tegmental area (VTA), upregulates dopaminergic system in the basolateral amygdala (BLA), enabling the expression of conditioned freezing response.
Contextual control over expression of fear is affected by cortisol
TLDR
The results indicated that people rapidly acquire differential contextual modulation of the expression of fear, as measured by fear potentiated startle (FPS) and skin conductance responses (SCR) and cortisol impaired differential conditioning in men.

TLDR
The amygdala becomes hyperactive in posttraumatic stress disorder (PTSD) and depressive illness, and hypertrophy of amygdala nerve cells is reported after repeated stress in an animal model.
Emotion, motivation, and the brain: reflex foundations in animal and human research.
TLDR
A motivational circuit in the brain, centered on the amygdala, that underlies human emotion is focused on, showing similar activation patterns in brain and body in response to emotion cues, co-varying with participants' reports of affective valence and increasing emotional arousal.
Previous Stress Facilitates Fear Memory, Attenuates GABAergic Inhibition, and Increases Synaptic Plasticity in the Rat Basolateral Amygdala
TLDR
The hypothesis that previous stress attenuates inhibitory GABAergic control in the BLA, leading to neuronal hyperexcitability and increased plasticity that facilitates fear learning is supported.

TLDR
The working hypothesis is that structural plasticity in response to repeated stress starts out as an adaptive and protective response, but ends up as damage if the imbalance in the regulation of the key mediators is not resolved.
Endocrinology of the stress response.
The stress response is subserved by the stress system, which is located both in the central nervous system and the periphery. The principal effectors of the stress system include
Corticosteroids in relation to fear, anxiety and psychopathology

TLDR
The present review shows that different aspects of fear and anxiety are affected differentially by the occupation of the mineralocorticoid receptor (MR) or glucoc Corticosteroids (GR) at different phases of the stress response.
Exposure to Acute Stress Blocks the Induction of Long-Term Potentiation of the Amygdala–Prefrontal Cortex Pathway In Vivo
TLDR
Whether stress, which impairs hippocampal long-term potentiation (LTP), also affects LTP of the basolateral amygdala (BLA)–PFC pathway in vivo is examined and results indicate that, at the same time when LTP is blocked in the hippocampus, it is also inhibited in the BLA–medial PFC pathway.
Stress and hippocampal plasticity: implications for the pathophysiology of affective disorders
TLDR
From a therapeutic standpoint, it is essential to distinguish between permanent damage and reversible atrophy in order to develop treatment strategies to either prevent or reverse deficits, and remodeling of brain cells may occur in other brain regions.
The Prefrontal Cortex as a Key Target of the Maladaptive Response to Stress
TLDR
It is demonstrated that short periods of stress exposure induce spatial reference memory deficits before affecting PFC-dependent tasks, thus suggesting that the impairment of synaptic plasticity within the hippocampus-to-PFC connection is of relevance to the stress-induced PFC dysfunction.
Hormones and the Stressed Brain
TLDR
The yin‐yang concept in stress regulation is fundamental for genomic strategies to understand the mechanistic underpinning of corticosteroid‐induced stress‐related disorders such as severe forms of depression.
