The biology of being frazzled

Arnsten, Amy F. T.·1998·Science

Abstract

Under stress, our brain works differently. From our own experiences we know this, but now several lines of research are defining the neurobiology behind these changes. In her commentary, Arnsten summarizes recent work that demonstrates that some kinds of memory become enhanced (such as the image of a gruesome accident), while higher order thinking, mediated by a region of the brain called the prefrontal cortex, becomes impaired.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The types of tasks impaired by stress are those requiring prefrontal cortex operations, whereas engrained habits relying on basal ganglia circuits are spared or enhanced.

    “We now understand that the types of tasks that were impaired by stress were those that required PFC operations13, whereas engrained habits that rely on basal ganglia circuits were spared or enhanced14.”
  • Exposure to an acute, uncontrollable stress impairs the performance of PFC cognitive tasks in rodents, monkeys and humans.

    “Exposure to an acute, uncontrollable stress impairs the performance of PFC cognitive tasks in rodents, monkeys and humans25.”
  • Adolescents are particularly prone to have their decision-making influenced by exciting, emotionally charged, or stressful situations.

    “adolescents seem particularly prone to have their decision-making influenced by exciting, emotionally charged and/or stressful situations”
  • Adolescents are particularly prone to decision-making influenced by exciting, emotionally charged, or stressful situations (hot cognitions).

    “adolescents seem particularly prone to have their decision-making influenced by exciting, emotionally charged and/or stressful situations (so called “hot cognitions” – e.g., Arnsten, 1998; Dahl, 2001; Figner et al, 2009).”
  • Stressors tend to increase activation in ventral striatum, amygdala, and hippocampus, while attenuating functional efficacy within PFC.

    “stressors tending to increase activation in the ventral striatum, amygdala and other subcortical regions such as the hippocampus, while attenuating functional efficacy within the PFC (Arnsten, 1998, Liston et al, 2009)”

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.
