Abstract

The present experiment was designed to explore the stress-relatedness of activity in noradrenergic neurons of the locus coeruleus (LC) of behaving cats. A stressor was defined as a stimulus that elicited a significant sympathoadrenal activation as measured by plasma norepinephrine level and heart rate. According to this definition, exposure to 15 min of 100 dB white noise or 15 min of restraint was stressful in cats. In contrast, exposure to inaccessible rats for 15 min was behaviorally activating but nonstressful. The single-unit activity of noradrenergic neurons in the LC of behaving cats was examined under these conditions. The stressful stimuli elicited a significant increase in LC neuronal activity for the entire 15 min stressor duration, whereas the behaviorally activating but nonstressful stimulus elicited no significant change in the activity of these neurons. These results provide evidence that behavioral activation per se is not sufficient to evoke a tonic activation of these neurons. Rather, these data support the hypothesis that the LC is involved in the CNS response to stress and provide additional evidence that the activity of LC noradrenergic neurons increases in association with sympathoadrenal activation.

  • Studies in animals show that early stressors lead to increased activity of the locus coeruleus with resultant increased release of nor-epinephrine in the brain.

    “Studies in animals show that early stressors lead to increased activity of the locus coeruleus with resultant increased release of nor-epinephrine in the brain (Abercrombie and Jacobs 1987).”

    From The enduring effects of abuse and related adverse experiences in childhood: A convergence of evidence from neurobiology and epidemiology (2006) · cites this paper as Abercrombie and Jacobs 1987

    The Summary (p. 2843) reports increased locus coeruleus activity during acute stress in freely moving cats. The paper does not study early-life stressors or measure norepinephrine release in the brain; its introduction describes earlier evidence as indirect measures of central norepinephrine utilization.

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.
