The ability of oxytocin to induce short latency maternal behavior is dependent on peripheral anosmia.

Wamboldt, Marianne Z., Insel, Thomas R.·1987·Behavioral Neuroscience

Abstract

Nulliparous female Sprague-Dawley rats, cannulated in the left lateral ventricle, were ovariectomized and estrogen primed, then either rendered anosmic via intranasal irrigation with zinc sulfate or left with intact olfaction. Forty-eight hr later, after a 2-hr habituation to the test cage, these animals were injected with either intracerebroventricular oxytocin (400 ng in 2 microliter saline) or saline (2 microliter). Only the group receiving both zinc sulfate and oxytocin became maternal. Additionally, approximately one third of the olfaction-intact rats and none of the anosmic rats cannibalized the rat pups. These results are discussed in regard to discrepancies in the literature regarding oxytocin's role in inducing maternal behavior, as well as the functional connection of the olfactory and oxytocin systems.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Neuropeptide neurons can release peptide from its entire surface area and can diffuse through the extracellular space due to long half-lives.

    “Unlike classical neurotransmitters, which are released primarily at the synaptic cleft, neuropeptide neurons can release peptide from its entire surface area [131] and can diffuse through the extracellular space due to long half-lives.”

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.
