Conditioned fear is supported by a distributed network that prominently includes lateral and central amygdaloid nuclei. The role of corticomedial amygdaloid nuclei, including the medial nucleus (MeA), in fear acquisition or expression is not well understood. The present study demonstrates that pre-training excitotoxic lesions directed at the MeA disrupted both fear-potentiated startle (FPS) and conditioned freezing behavior elicited by re-exposure to a discrete olfactory cue. In contrast, such… 
Incubation of Fear Is Regulated by TIP39 Peptide Signaling in the Medial Nucleus of the Amygdala
TLDR
The findings demonstrate that TIP39 signaling within the MeA at the time of an aversive event regulates the increase over time in fear associated with the event context, which will help in the understanding of why traumatic events sometimes have severe psychological consequences.
Midazolam treatment before re-exposure to contextual fear reduces freezing behavior and amygdala activity differentially in high- and low-anxiety rats
TLDR
It is demonstrated that LR rats are more sensitive to re-exposure to fear stimuli and that midazolam pretreatment was associated with modified brain activity in the amygdala and in the prefrontal cortex in this group of animals.
Anterior olfactory organ removal produces anxiety-like behavior and increases spontaneous neuronal firing rate in basal amygdala
TLDR
The present results suggest the participation of SO-VNO/accessory olfactory bulb/basal amygdala relationships in the regulation of anxiety through a process of disinhibition.
Amygdala: Structure and Function
The amygdala is considered a key center in managing emotional information and its dysfunction is at the base of disorders ranging through anxiety, depression, PTSD and autism. However, the amygdala
Afferent projections to the different medial amygdala subdivisions: a retrograde tracing study in the mouse
TLDR
The common pattern of afferents to the Me subdivisions and their interconnections suggest that they play cooperative instead of differential roles in the various behaviours in which the Me has been shown to be involved.
Assessment of sensorimotor gating following selective lesions of cholinergic pedunculopontine neurons
TLDR
Results show that cholinergic output from PPTg is essential for rapidly regenerating the ASR, but has no influence on PPI, which is widely viewed as mediating both PPI and ASR.
A food-predictive cue attributed with incentive salience engages subcortical afferents and efferents of the paraventricular nucleus of the thalamus
TLDR
Presentation of an incentive stimulus results in engagement of subcortical brain regions; supporting a role for the hypothalamic-thalamic-striatal axis, as well as the MeA, in mediating responses to incentive stimuli; whereas activity in the PrL to PVT pathway appears to play a role in processing the predictive qualities of reward-paired stimuli.
The elusive rat model of conditioned placebo analgesia
TLDR
It is concluded that placebo analgesia in rats is not particularly robust and that it is difficult to achieve using conventional procedures and proper experimental design.
Investigating the Role of Testosterone Signaling at Androgen Receptors in Resiliency to Social Stress
TLDR
This study investigated whether winning aggressive interactions increases plasma testosterone and whether repeatedly winning increases androgen receptor expression and whether 14 days of dominant social status increased androgen or estrogen alpha-receptor immunoreactivity in brain regions that regulate the conditioned defeat response.
Role of Oestrogen α Receptors in Sociosexual Behaviour in Female Rats Housed in a Seminatural Environment
TLDR
A reduction of ERα expression in the VMN or POA diminished the display of paracopulatory behaviours and lordosis responses compared to controls, whereas the lordosis quotient remained unaffected, which suggests that ERα in theVMN and POA play an important role in intrinsic sexual motivation.

Both Pre- and Posttraining Excitotoxic Lesions of the Basolateral Amygdala Abolish the Expression of Olfactory and Contextual Fear Conditioning
The present study examined whether the basolateral amygdaloid complex (BLA) participates in the expression of fear conditioned to both an olfactory conditioned stimulus (CS) and the training context.
Nucleus accumbens carbachol disrupts olfactory and contextual fear-potentiated startle and attenuates baseline startle reactivity
TLDR
It is suggested that NAc cholinergic receptors play a role in the modulation of baseline startle reactivity, rather than in the retrieval of learned fear, and that this role is independent of overt motor activity.
Medial amygdala lesions differentially influence stress responsivity and sensorimotor gating in rats
TLDR
The present study suggests that the medial amygdala is an important player in response to acute environmental stimuli, whereas LES was enhanced and sensorimotor processing was disrupted.
Patterns of Fos expression in the amygdala and ventral perirhinal cortex induced by training in an olfactory fear conditioning paradigm.
TLDR
The activation of amygdaloid nuclei, the ventral perirhinal cortex (vPRh), and several other brain areas in the rat during the acquisition and expression of olfactory fear conditioning was assessed through Fos immunocytochemistry to suggest that the aMe and vPRh may be critically involved in different aspects of o aroma fear conditioning.
New vistas on amygdala networks in conditioned fear.
TLDR
It is suggested that potentiated LA outputs disinhibit CE projection neurons via GABAergic intercalated neurons, thereby permitting associative plasticity in CE, and accounts for inhibition of conditioned fear after extinction.
The lateral amygdaloid nucleus: sensory interface of the amygdala in fear conditioning
TLDR
AL is an essential link in the circuitry through which auditory stimuli are endowed with affective properties and may function as the sensory interface of the amygdala during emotional learning.
Damage to the lateral and central, but not other, amygdaloid nuclei prevents the acquisition of auditory fear conditioning.
TLDR
It is shown that only the lateral and central nuclei are necessary for the acquisition of conditioned fear response to an auditory conditioned stimulus.
Glutamate receptor antagonist infusions into the basolateral and medial amygdala reveal differential contributions to olfactory vs. context fear conditioning and expression.
TLDR
An unexpected dissociation of the basolateral amygdala's involvement in discrete cue versus context fear and fear conditioning is revealed, and for the first time the medial amygdala is implicate in fear-potentiated startle testing.
Modulation of memory consolidation for olfactory learning by reversible inactivation of the basolateral amygdala.
TLDR
The finding that rats receiving tetrodotoxin infusions following paired odor-shock presentations spent more time near the odor, and reacted differently on contact with the odor when tested 24 hr after training, strengthens the view that the BLA plays a general role in modulation of memory storage for emotionally arousing events.
Dopamine-mediated modulation of odour-evoked amygdala potentials during pavlovian conditioning
TLDR
In vivo intracellular recordings to examine LAT neurons during pavlovian conditioning in rats found that repeated pairings of an odour with a foot-shock resulted in enhanced post-synaptic potential (PSP) responses to the odour and increased neuronal excitability, however, a non-paired odour displayed PSP decrement.
