The right amygdala is associated with response to fearful stimuli as well as face recognition. For the left amygdala, it is inferred that the early development of it functions to provide infants the ability to detect danger due to its reported responds predominantly to fearful events and faces.

2016年4月30日 · Differential insula connectivity to the amygdala among dissociative subtype patients. Suggests unique neural circuit biomarkers of PTSD and its dissociative subtype. Insula connectivity results parallel the unique symptom profiles of each PTSD group.

It was found that PTSD patients were able to successfully downregulate both right and left amygdala activation, showing sustained effects within the transfer run. Increased activation in the dorsolateral and ventrolateral prefrontal cortex (PFC), regions related to emotion regulation, was observed during regulate as compared with view conditions.

2019年2月28日 · Borderline personality disorder (BPD) is characterized by pronounced emotional instability in interpersonal relations. Previous studies have shown increased activity in the amygdala, an imaging phenotype of negative affect.

2017年7月25日 · Here, we studied the effects of both the menstrual cycle and oral contraceptives (OCs) on amygdala and salience network resting-state functional connectivity using a double-blind, randomized, and...

Neurological Institute standard space. Using MRIcron, a mask was drawn over the lesion and any craniotomy defect, where masked voxels were assigned a weight of 0, elsewise 1—indicating the presence of intact tissue. Two frontal patients had bilateral damage spanning both the right and left hemispheres. In a few cases, the damage was highly

Statistically significant increases in activation in response to emotion recognition in individuals with SAD compared with healthy controls was found in the following areas: the right amygdala (x = 26, y = −8, z = −20), left amygdala (x = −22, y = −4, z = −22), left medial temporal lobe encompassing amygdala and entorhinal cortex ...

2020年2月4日 · In this study, we used resting-state functional magnetic resonance imaging (rs-fMRI) and diffusion tensor imaging (DTI) to examine the potential functional and structural connectivity abnormalities within amygdala-prefrontal circuit in first-episode medication-naïve adolescents with MDD.

2017年10月13日 · Whole-brain analyses revealed post-treatment decreases in CBF in the temporal cortex, including the amygdala. Decreased amygdala CBF correlated with reduced depressive symptoms.

2018年6月4日 · Therefore, the evolution over time of the fMRI signal from the amygdala seems to be a critical element to discriminate between habituation due to repeated presentation of the assay and changes in primary amygdala reactivity due …
