Abstract

Norepinephrine (NE) release in the medial prefrontal cortex (PFC) of rats was studied during immobilization using an intracerebral microdialysis technique. A series of experiments using pharmacological and physiological manipulations indicated that the NE recovered in the medial PFC dialysate was mainly derived from nerve terminals and that the dorsal noradrenergic bundle was a major source of NE in the medial PFC. Immobilization stress immediately elevated NE levels to 176.0 +/- 9.0% of basal release, and this increase continued for the entire period of stress and 20 min after termination of the stress. Preinjection of a benzodiazepine receptor agonist, diazepam (5 mg/kg ip), significantly attenuated immobilization-induced NE release, while injection of an anxiogenic compound, FG-7142 (20 mg/kg ip), facilitated NE release in an obviously nonstressed condition. These results therefore suggest that stressful stimuli activate the NE system in the medial PFC, which may be modulated by an activation of benzodiazepine receptors in the brain.

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?

  • Stress activates the noradrenergic neurons of the locus coeruleus via stimulation by the amygdala of corticotropin-releasing factor (CRF) receptors on locus coeruleus neurons, increasing norepinephrine release in PFC.

    “Stress also activates the noradrenergic neurons of the locus coeruleus via stimulation by the amygdala of corticotropin-releasing factor (CRF) receptors on locus coeruleus neurons48, increasing norepinephrine release in PFC49.”

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.
