PS07. Neuronal encoding of anxiety in the bed nucleus of the stria terminalis
s | 3 reinstatement was accompanied by reduction of synaptic input in the IL. Then we hypothesized that prefrontal dopamine plays a key role in reinstatement and tested this idea. A reminder shock induced c-Fos expression in the IL-projecting dopaminergic neurons in the ventral tegmental area. Blocking of IL dopamine D1 receptor signaling prevented reduction of synaptic input, CeM c-Fos express...
متن کاملThe bed nucleus of the stria terminalis mediates inter-individual variations in anxiety and fear.
While learning to fear stimuli that predict danger promotes survival, the inability to inhibit fear to inappropriate cues leads to a pernicious cycle of avoidance behaviors. Previous studies have revealed large inter-individual variations in fear responding with clinically anxious humans exhibiting a tendency to generalize learned fear to safe stimuli or situations. To shed light on the origin ...
متن کاملOrbitofrontal cortex lesions alter anxiety-related activity in the primate bed nucleus of stria terminalis.
In children, behavioral inhibition (BI) in response to potential threat predicts the development of anxiety and affective disorders, and primate lesion studies suggest involvement of the orbitofrontal cortex (OFC) in mediating BI. Lesion studies are essential for establishing causality in brain-behavior relationships, but should be interpreted cautiously because the impact of a discrete lesion ...
متن کاملCalcitonin gene-related peptide in the bed nucleus of the stria terminalis produces an anxiety-like pattern of behavior and increases neural activation in anxiety-related structures.
Calcitonin gene-related peptide (CGRP) evokes anxiety-like responses when infused into the lateral ventricle of rats. Because the bed nucleus of the stria terminalis (BNST) lies immediately adjacent to the lateral ventricle, is rich in CGRP receptors, and has itself been implicated in anxiety, we evaluated the hypothesis that these effects are attributable to stimulation of CGRP receptors withi...
