Oxytocin activates the postpartum onset of rat maternal behavior in the ventral tegmental and medial preoptic areas.

Abstract

Oxytocin binding (Bmax) was found to be higher in the ventral tegmental area (VTA) and the medial preoptic area (MPOA) at midparturition compared with Pregnancy Days 15-17 or Postpartum Days 5-7 in rat dams. Pup retrieval and assuming a nursing posture over pups were blocked in parturient dams by infusions of an oxytocin antagonist into the VTA or MPOA and by infusions of a vasopressin (V1) antagonist into the MPOA. These results implicate oxytocin in the VTA and MPOA and vasopressin in the MPOA, as well as a parturition-associated rise in oxytocin binding in these sites in the postpartum activation of maternal behavior.

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?

  • Onset of maternal behavior can be prevented by injection of an OTR antagonist into the VTA.

    “The onset of maternal behavior can be prevented by injection of an OTR antagonist into the VTA (Pedersen et al 1994).”
  • The oxytocin and dopaminergic systems work in concert to promote rodent maternal behaviors.

  • Oxytocin antagonists applied within the VTA impair both pup retrieval and time spent in nursing postures over pups in parturient dams.

    “whereas oxytocin antagonists applied within the VTA impair both pup retrieval and time spent in nursing postures over pups in parturient dams (Pedersen et al., 1994).”

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.
