Increased Inhibition of the Amygdala by the mPFC may Reflect a Resilience Factor in Post-traumatic Stress Disorder: A Resting-State fMRI Granger Causality Analysis

open access: yesFrontiers in Psychiatry, 2018
Purpose: To determine whether effective connectivity of the amygdala is altered in traumatized subjects with and without post-traumatic stress disorder (PTSD).Materials and Methods: Resting-state functional MRI data were obtained for 27 patients with ...

Amygdala connectivity related to subsequent stress responses during the COVID-19 outbreak

open access: yesFrontiers 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 ...

Functional connectivity of intercalated nucleus with medial amygdala: A circuit relevant for chemosignal processing

open access: yesIBRO Neuroscience Reports, 2022
Medial amygdala processes social/reproductive chemosensory input, and its projections to preoptic and hypothalamic areas evoke appropriate behavioral and physiological responses.

Stress-induced cortisol response is associated with right amygdala volume in early childhood

open access: yesNeurobiology of Stress, 2021
Rodent research suggests that dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis and the resulting cortisol stress response can alter the structure of the hippocampus and amygdala.

Amygdala reactivity predicts adolescent antisocial behavior but not callous-unemotional traits. [PDF]

open access: yes, 2017
Recent neuroimaging studies have suggested divergent relationships between antisocial behavior (AB) and callous-unemotional (CU) traits and amygdala reactivity to fearful and angry facial expressions in adolescents.

COMPARISON OF EMOTIONAL RESPONSES IN MONKEYS WITH RHINAL CORTEX OR AMYGDALA LESIONS [PDF]

open access: yes, 2002
Four emotionally arousing stimuli were used to probe the behavior of monkeys with bilateral ablations of the entorhinal and perirhinal cortex. The animals’ behavioral changes were then contrasted with those observed earlier (Meunier et al., 1999) in ...

Differential Input from the Amygdaloid Body to the Ventromedial Hypothalamic Nucleus in the Rat [PDF]

open access: yes, 1983
Differential amygdaloid afferents to anterior dorsal, anterior ventral, posterior dorsal and posterior ventral subdivisions of the ventromedial hypothalamic nucleus (VMH) were studied by means of retrograde transport of horseradish peroxidase (HRP ...
