Chemical Lesion of the Bed Nucleus of the Stria Terminalis Blocks the Behavioral Consequences of Uncontrollable Stress.

Abstract

Uncontrollable or inescapable shock (IS) produces behavioral changes that are characterized by a sensitized fear system and a deficit in fight-flight responding. These behavioral changes have been argued to represent an anxiety-like state produced by the uncontrollability of the stressor. The bed nucleus of the stria terminalis (BNST) has been implicated in the mediation of long-duration responses to unpredictable stressors, which have also been argued to represent anxiety. In the present study, the effects of BNST chemical lesion on the IS-induced sensitization of freezing to an environment previously paired with shock and the IS-induced impairment of escape responding were investigated. BNST chemical lesion blocked the potentiation of freezing and the increases in escape latency that normally follow IS.

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.
