Abstract

Neuroimaging serves as an effec-tive way to investigate the neu-rocircuitry involved in the de-velopment of posttraumatic stress disorder (PTSD).1-3 A number of models describing functional neuroanatomy of PTSD symp-tom development emerged over the past decade, inspired by both basic animal re-search and an increasing number of human neuroimaging studies. These models have traditionally conceptualized PTSD as a state of heightened responsivity to threat-ening stimuli and later as a state of insuf-fi cient inhibitory control over-exaggerated threat-sensitivity. They emphasize the cen-trality of threat-related processing in the pathophysiology of PTSD and therefore

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.
