Maternal communication of circadian phase to the developing mammal

Reppert, S·1988·Psychoneuroendocrinology

Abstract

In rodents, an entrainable circadian clock begins oscillating prenatally in the hypothalamic suprachiasmatic nuclei (SCN). The maternal circadian system coordinates (entrains) the timing of the developing clock to the prevailing light-dark cycle during both late fetal and early neonatal life. This maternal communication of circadian phase ensures that the developing animal is coordinated to the outside world until maturation of the normal pathway of light-dark entrainment in adults, the retinohypothalamic pathway, permits direct photic entrainment through the neonatal eye. The mechanism of maternal communication of circadian phase remains to be determined, but the necessity of the maternal SCN in this communication has been demonstrated. Indirect lines of evidence suggest that a similar scheme occurs for the development of circadian rhythms in humans.

  • In humans, melatonin and dopamine receptors appear as early as gestational week 18 in the fetal SCN, suggesting melatonin and dopamine may serve as the primary communicators of circadian information for the fetus.

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.
