Intrinsic functional connectivity of the central nucleus of the amygdala and bed nucleus of the stria terminalis
The central nucleus of the amygdala (CeA) and bed nucleus of the stria terminalis (BNST), two nuclei within the central extended amygdala, function as critical relays within the distributed neural networks that coordinate sensory, emotional, and cognitive responses to threat. These structures have overlapping anatomical projections to downstream targets that initiate defensive responses. Despit...
متن کاملActivity alterations in the bed nucleus of the stria terminalis and amygdala during threat anticipation in generalized anxiety disorder
Sustained anticipatory anxiety is central to Generalized Anxiety Disorder (GAD). During anticipatory anxiety, phasic threat responding appears to be mediated by the amygdala, while sustained threat responding seems related to the bed nucleus of the stria terminalis (BNST). Although sustained anticipatory anxiety in GAD patients was proposed to be associated with BNST activity alterations, firm ...
متن کاملSexual dimorphism of the bed nucleus of the stria terminalis and the amygdala.
The present review summarizes the up-to-date knowledge on the sexual dimorphism of the CNS with special regard to the sexual differentiation of the bed nucleus of the stria terminalis (BST) and the amygdala in rat. The authors provide new evidence for the sexual dimorphism and differentiation of GABAergic, leucine-enkephalin-containing and parvalbumin-immunoreactive neurons in the BST and the a...
متن کاملUnsmoothed functional MRI of the human amygdala and bed nucleus of the stria terminalis during processing of emotional faces
Functional neuroimaging of the human amygdala has been of great interest to uncover the neural underpinnings of emotions, mood, motivation, social cognition, and decision making, as well as their dysfunction in psychiatric disorders. Yet, several factors limit in vivo imaging of amygdalar function, most importantly its location deep within the temporal lobe adjacent to air-filled cavities that ...
متن کاملHuman bed nucleus of the stria terminalis indexes hypervigilant threat monitoring.
BACKGROUND Though a key symptom underlying many anxiety disorders is hypervigilant threat monitoring, its biological bases in humans remain poorly understood. Animal models suggest that anxious processes such as hypervigilant threat monitoring are distinct from cued fear-like responses and mediated by the bed nucleus of the stria terminalis (BNST). Here, we applied psychophysiological and neuro...
