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 کاملAmygdala and bed nucleus of the stria terminalis: differential roles in fear and anxiety measured with the acoustic startle reflex.
Neural stimuli associated with traumatic events can readily become conditioned so as to reinstate the memory of the original trauma. These conditioned fear responses can last a lifetime and may be especially resistant to extinction. A large amount of data from many different laboratories indicate that the amygdala plays a crucial role in conditioned fear. The amygdala receives information from ...
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 کاملRole of the bed nucleus of the stria terminalis versus the amygdala in fear, stress, and anxiety.
The bed nucleus of the stria terminalis is a limbic forebrain structure that receives heavy projections from, among other areas, the basolateral amygdala, and projects in turn to hypothalamic and brainstem target areas that mediate many of the autonomic and behavioral responses to aversive or threatening stimuli. Despite its strategic anatomical position, initial attempts to implicate the bed n...
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 ...
