An fMRI study examining the role of the extended amygdala and amygdala in emotion and inhibitory control in native versus second language processing.

PLoS ONE
The role of the extended amygdala and amygdala in mediating emotion and inhibitory control in native language versus second language processing is currently not well understood.

Increased anxiety-like behavior and enhanced synaptic efficacy in the amygdala of GluR5 knockout mice.

PLoS ONE, 2007
GABAergic transmission in the amygdala modulates the expression of anxiety. Understanding the interplay between GABAergic transmission and excitatory circuits in the amygdala is, therefore, critical for understanding the neurobiological basis of anxiety.

Optogenetic dissection of amygdala functioning

Frontiers in Behavioral Neuroscience, 2014
Studies of amygdala functioning have occupied a significant place in the history of understanding how the brain controls behavior and cognition. Early work on the amygdala placed this small structure as a key component in the regulation of emotion and ...

Amygdala Nuclei Volumes Are Selectively Associated With Social Network Size in Homeless and Precariously Housed Persons

Frontiers in Behavioral Neuroscience, 2020
Objective: The amygdala is a brain region comprised of a group of functionally distinct nuclei that play a central role in social behavior. In homeless and precariously housed individuals, high rates of multimorbidity, and structural aspects of the ...

Microcircuits of the Amygdala [PDF]

, 2017
This chapter reviews the unique microcircuits within the subdivisions of the amygdala. Microcircuits of the amygdala remain somewhat of an enigma. The amygdala itself is comprised of laterally located glutamatergic projection neuron structures, which are

Sustained, not habituated, activity in the human amygdala: A pilot fMRI dot-probe study of attentional bias to fearful faces

Cogent Psychology, 2016
The human amygdala consciously and nonconsciously processes facial expressions and directs spatial attention to them. Research has shown that amygdala activity habituates after repeated exposure to emotionally salient stimuli during passive viewing tasks.

Gastrin-releasing peptide signaling plays a limited and subtle role in amygdala physiology and aversive memory. [PDF]

PLoS ONE, 2012
Links between synaptic plasticity in the lateral amygdala (LA) and Pavlovian fear learning are well established. Neuropeptides including gastrin-releasing peptide (GRP) can modulate LA function. GRP increases inhibition in the LA and mice lacking the GRP

Fear recognition ability predicts differences in social cognitive and neural functioning in men [PDF]

, 2006
By testing the facial fear-recognition ability of 341 men in the general population, we show that 8.8% have deficits akin to those seen with acquired amygdala damage.

Angst and the amygdala

Dialogues in Clinical Neuroscience, 2006
Fear is an adaptation to danger, but excessive fear underlies diverse forms of mental anguish and pathology. One neural site linked to a sense of adversity is the amygdala, and one neuropeptide, corticotropin-releasing hormone (CRH), is localized within the central nucleus of the amygdala. Glucocorticoids enhance the production of CRH in this region of
