American Journal of Psychiatry, 2015 results present an explanatory challenge: why would the amygdala be hypoactive in paranoid individuals who exhibit heightened threat perception and elevated physiological arousal? To explain this paradoxical finding, some investigators hypothesized that reduced frontal control over the amygdala due to dysconnectivity of frontolimbic circuitry could ...

Surface morphology of amygdala is associated with trait anxiety. [PDF]
PLoS ONE, 2012 Previous neuroimaging studies have suggested a role of amygdala in trait anxiety level, in which amygdala was typically treated as a whole. To date, it remains unknown whether the morphology of specific subregions of amygdala are associated with trait ...

The central amygdala controls learning in the lateral amygdala [PDF]
Nature Neuroscience, 2017 Experience-driven synaptic plasticity in the lateral amygdala is thought to underlie the formation of associations between sensory stimuli and an ensuing threat. However, how the central amygdala participates in such a learning process remains unclear. Here we show that PKC-δ-expressing central amygdala neurons are essential for the synaptic plasticity

Insecure attachment during infancy predicts greater amygdala volumes in early adulthood [PDF]
, 2014 Background The quality of the early environment is hypothesized to be an influence on morphological development in key neural areas related to affective responding, but direct evidence to support this possibility is limited.

Preoperative amygdala fMRI in temporal lobe epilepsy [PDF]
, 2009 Purpose: Anterior temporal lobe resections (ATLR) benefit 70% of patients with refractory mesial temporal lobe epilepsy (TLE), but may be complicated by emotional disturbances.

Response properties of human amygdala subregions : evidence based on functional MRI combined with probabilistic anatomical maps [PDF]
, 2007 The human amygdala is thought to play a pivotal role in the processing of emotionally significant sensory information. The major subdivisions of the human amygdala—the laterobasal group (LB), the superficial group (SF), and the centromedial group (CM ...

Amygdala connectivity related to subsequent stress responses during the COVID-19 outbreak
Frontiers in Psychiatry, 2023 IntroductionThe amygdala plays an important role in stress responses and stress-related psychiatric disorders. It is possible that amygdala connectivity may be a neurobiological vulnerability marker for stress responses or stress-related psychiatric ...
