Abstract

Background Stress-induced metabolic changes can have detrimental health effects. Newly developed paradigms to investigate stress in neuroimaging environments allow the assessment of brain activation changes in association with the perception of and the metabolic response to stress.Methods We exposed human subjects to a psychosocial stressor in one positron emission tomography (n = 10) and one functional magnetic resonance imaging (fMRI; n = 40) experiment.Results We observed a profound deactivation of limbic system components including hippocampus, hypothalamus, medio-orbitofrontal cortex and anterior cingulate cortex in subjects who reacted to the stressor with a significant increase of the endocrine stress marker cortisol. Further, in the fMRI study, the degree of deactivation in the hippocampus was correlated with the release of cortisol in response to the stress task.Conclusions The observed deactivation of limbic system structures suggests elevated activation at rest and during nonstressful situations. A model is proposed where the observed reduction in limbic system activity is essential for the initiation of the stress response.

  • Prefrontal regions affected by high pregnancy anxiety are involved in regulation of stress hormone secretion.

    “Interestingly, a recent functional MRI study in humans found that prefrontal regions, that we found are affected by high pregnancy anxiety, are involved in the regulation of stress hormone secretion (Pruessner et al., 2008).”
  • Dagher et al (2009) found that a psychosocial stressor task elicited widespread limbic changes including BNST activity, and that these limbic changes predicted subsequent increased BNST activity to smoking cues in nicotine-addicted participants.

    “In a study of nicotine-addicted participants, Dagher et al (2009) showed that a psychosocial stressor task elicited widespread changes in limbic (including BNST) activity-a marker of stress response (Pruessner et al, 2008) -and that changes in limbic activity were predictive of subsequent increased BNST activity to smoking cues.”

  • Changes in limbic activity have been proposed as a marker of stress response, and limbic activity size is proportional to cortisol release during stress.

    “Changes in limbic activity have been proposed to be a marker of stress response, and limbic activity is proportional in size to cortisol release during stress (Pruessner et al, 2008).”

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.
