Abstract

Attentional biases have been proposed to contribute to symptom maintenance in posttraumatic stress disorder (PTSD), although the neural correlates of these processes have not been well defined; this was the goal of the present study. We administered an attention bias task, the dot probe, to a sample of 37 (19 control, 18 PTSD+) traumatized African-American adults during fMRI. Compared to controls, PTSD+ participants demonstrated increased activation in the dorsolateral prefrontal cortex (dlPFC) in response to threat cue trials. In addition, attentional avoidance of threat corresponded with increased ventrolateral prefrontal cortex (vlPFC) and dorsal anterior cingulate cortex (dACC) activation in the PTSD group, a pattern that was not observed in controls. These data provide evidence to suggest that relative increases in dlPFC, dACC and vlPFC activation represent neural markers of attentional bias for threat in individuals with PTSD, reflecting selective disruptions in attentional control and emotion processing networks in this disorder.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • First evidence from studies in healthy participants and patients with generalized anxiety disorder, posttraumatic stress disorder, or panic disorder suggests involvement of dorsolateral, dorsomedial, and ventrolateral aspects of the prefrontal cortex in processing the attention bias towards threat-related stimuli.

    “First evidence from studies in healthy participants [17] as well as patients with generalized anxiety disorder [18]–[20], posttraumatic stress disorder [21], or panic disorder [22] suggests an involvement of dorsolateral [17], [19]–[21], dorsomedial [21], and ventrolateral [18], [21], [22] aspects of the prefrontal cortex in the processing of the attention bias towards threat-related stimuli.”

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.
