Neural systems involved in fear and anxiety measured with fear-potentiated startle.

Davis, Michael·2006·American Psychologist

Abstract

A good deal is now known about the neural circuitry involved in how conditioned fear can augment a simple reflex (fear-potentiated startle). This involves visual or auditory as well as shock pathways that project via the thalamus and perirhinal or insular cortex to the basolateral amygdala (BLA). The BLA projects to the central (CeA) and medial (MeA) nuclei of the amygdala, which project indirectly to a particular part of the acoustic startle pathway in the brainstem. N-methyl-D-aspartate (NMDA) receptors, as well as various intracellular cascades in the amygdala, are critical for fear learning, which is then mediated by glutamate acting in the CeA. Less predictable stimuli, such as a long-duration bright light or a fearful context, activate the BLA, which projects to the bed nucleus of the stria terminalis (BNST), which projects to the startle pathway much as the CeA does. The anxiogenic peptide corticotropin-releasing hormone increases startle by acting directly in the BNST. CeA-mediated behaviors may represent stimulus-specific fear, whereas BNST-mediated behaviors are more akin to anxiety. NMDA receptors are also involved in extinction of conditioned fear, and both extinction in rats and exposure-based psychotherapy in humans are facilitated by an NMDA-partial agonist called D-cycloserine.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
