The amygdala has long been thought to be involved in emotional behaviour, and its role in anxiety and conditioned fear has been highlighted. Individual amygdaloid nuclei have been shown to project to various cortical and subcortical regions implicated in affective processing. Here we show that some of these nuclei have separate roles in distinct mechanisms underlying conditioned fear responses. Rats with lesions of the central nucleus exhibited reduction in the suppression of behaviour elicited… 
Dissociable roles of the central and basolateral amygdala in appetitive emotional learning
TLDR
Results not only support the hypothesis that the amygdala is critical for appetitive as well as aversive learning, but are also consistent with amygdala subsystems subserving distinct aspects of emotional learning.
Different lateral amygdala outputs mediate reactions and actions elicited by a fear-arousing stimulus
TLDR
Activation of the LA by a CS seems to trigger conditioned reactions via CE and conditioned aversion via B activation, reduction of which reinforces new actions.
Amygdala circuitry in attentional and representational processes
TLDR
Recent evidence that links the amygdala to several aspects of food-motivated associative learning, including functions often characterized as attention, reinforcement and representation is discussed.
The Role of the Central Nucleus of the Amygdala in Mediating Fear and Anxiety in the Primate
TLDR
Results suggest that similar to rodent species, the primate CeA plays a role in mediating fear- and anxiety-related behavioral and endocrine responses and patterns of asymmetric frontal brain electrical activity, as assessed by regional scalp EEG, did not significantly differ between control and lesioned monkeys.
Opposing Influence of Basolateral Amygdala and Footshock Stimulation on Neurons of the Central Amygdala
TLDR
The results demonstrate that, contrary to conventional views, BLA stimulation primarily inhibits Cem neurons by a polysynaptic circuit, and show that single CEM neurons respond to both BLA input and footshock in an opposite manner.
The amygdala and appraisal processes: stimulus and response complexity as an organizing factor
TLDR
A modification of the traditional model of input pathways to the amygdala is proposed such that the LA activation as a sensory interface is limited to relatively simple, unimodal conditioned stimulus features whereas the basal amygdaloid nucleus (B) may serve as an amygdAloid sensory interface for complex, configural conditioned stimulus information.
Appetitive Behavior
TLDR
It is hypothesize that the basolateral amygdala is required for a conditioned stimulus to gain access to the current affective value of its specific unconditioned stimulus, whereas the central nucleus mediates stimulus‐response representations and conditioned motivational influences on behavior.
Inhibition of the Amygdala: Key to Pathological States?
TLDR
Future therapies aimed at increasing inhibitory tone in the amygdala, either locally or via the prefrontal cortex, may prevent anxiety disorders and addiction relapse, and novel neuropeptides offer promise in this regard.
The amygdala: securing pleasure and avoiding pain
TLDR
The interactions between different amygdala nuclei with cortical and striatal regions involved in motivation; interconnections and parallel circuitries that have become increasingly understood in recent years are discussed.
Contextual and auditory fear conditioning are mediated by the lateral, basal, and central amygdaloid nuclei in rats.
TLDR
There is significant overlap within the amygdala in the neural pathways mediating fear conditioning to contextual and acoustic CS, and that these forms of learning are not anatomically dissociable at the level of amygdaloid nuclei.

TLDR
The idea that the amygdala, and its many efferent projections, may represent a central fear system involved in both the expression and acquisition of conditioned fear is summarized.
The amygdala and emotion
TLDR
The use of animal models has progressively defined the circuitry for these functions within the amygdala and its interconnections with other brain systems, including pathways through which the amygdala modulates memory and regulates attention.

TLDR
A double dissociation of the effects of amygdala and hippocampal damage on fear conditioning to explicit and contextual cues is suggested.
Impaired auditory recognition of fear and anger following bilateral amygdala lesions
TLDR
A further investigation is reported of one of these rare cases, a woman who has impaired perception of the intonation patterns that are essential to the perception of vocal affect, despite normal hearing, which shows that the amygdala's role in the recognition of certain emotions is not confined to vision, which is consistent with its being involved in the appraisal of danger and the emotion of fear.

TLDR
