Diminished circadian rhythm of locomotor activity after vagotomy in rats.
Open accessAbstract
Circadian rhythm of spontaneous locomotor activity, which is normally highly elevated during the dark phase of a day, diminished after ablation of the vagal nerves in rats with intact suprachiasmatic nuclei under light-dark cyclic conditions. This suggests that gastrointestinal activity affects the circadian rhythm of locomotor activity through the afferent pathway of the vagus.

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.
