Abstract

Significance: Fear of negative outcomes has a powerful adverse influence on decision making in anxiety disorders. Although neuroimaging studies of patients with anxiety disorders have revealed dysregulation in numerous frontal brain regions including the orbitofrontal and ventrolateral prefrontal cortex, the causal involvement of this dysregulation is unknown. Here we demonstrate that in the marmoset monkey, inactivation of anterior orbitofrontal or ventrolateral prefrontal cortex increases negative bias in decision making via two distinct cognitive mechanisms—elevated uncertainty and attentional disruption, respectively. These findings provide, to our knowledge, the first direct evidence that dysregulation of distinct neurocognitive mechanisms within the prefrontal cortex may underlie the mixed etiology of anxiety disorders. Such insight will allow the development of more precise diagnostics and individually tailored therapeutic approaches.

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

  • Inactivation of area 11 induces negative biases based on memory of experiences, dependent on OFC interaction with amygdala and anterior hippocampus.

    “Conversely, inactivation of area 11 only induces negative biases based on the memory of those experiences, memories dependent on the OFC's interaction with the amygdala and anterior hippocampus [38].”

  • Inactivation of rostral central OFC (primarily area 11) and vlPFC in marmosets induces a negative bias in decision making.

    “Inactivation of more rostral regions of the central OFC (primarily area 11) and vlPFC in marmosets also induce a negative bias in decision making [38], although likely the result of distinct underlying psychological mechanisms.”

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.
