Oxytocin induces maternal behavior in virgin female rats

Pedersen, Cort A., Ascher, John A., Monroe, Yvonne L., Prange, Arthur J.·1982·Science

Abstract

Intracerebroventricular administration of oxytocin to virgin female rats that had been ovariectomized and primed with estrogen 48 hours previously induced a rapid onset of full maternal behavior. The maternal behavior persisted and its incidence was dose-related. Tocinoic acid, the ring structure of oxytocin, also rapidly induced the onset of persistent, full maternal behavior. Arginine vasopressin induced persistent maternal behavior, but this behavior had a later onset. Prostaglandin F2 alpha induced strong partial maternal behavior, which showed early onset but did not persist. Many other peptides, ovarian steroids, and prostaglandin E2 were no more effective than saline. These findings suggest that the release of oxytocin and prostaglandin F2 alpha during labor may promote maternal behavior in rats.

  • Oxytocin injection into the lateral cerebral ventricles of nulliparous/virgin rats rapidly induced maternal behaviors.

    “Pedersen et al. (1982) showed that oxytocin injection into the lateral cerebral ventricles of nulliparous/virgin rats rapidly induced maternal behaviors.”

  • In rats, 1-2 ng of oxytocin given intracerebroventricularly facilitates suckling-induced bursting, while maternal behavior requires about 400 ng; partner preference in voles requires 10-100 ng/h, and maternal behavior in sheep requires 5 μg intracerebroventricularly.

    “In lactating rats, suckling evokes bursts of action potentials in oxytocin cells that result in pulsatile oxytocin secretion, and this bursting is facilitated by 1-2ng oxytocin i.c.v.(26).Effects on maternal behavior in the rat need much higher doses (~400ng) (4).Partner preference effects in voles require infusions of oxytocin at 10-100ng/h (5), and, to stimulate maternal behavior in sheep, it”

  • The OT system undergoes dramatic changes during pregnancy and lactation to facilitate maternal behaviors.

    “the OT system undergoes dramatic changes during pregnancy and lactation to facilitate maternal behaviors (Jirikowski, Caldwell, Pilgrim, Stumpf, & Pendersen, 1989; Meddle, Bishop, Gkoumassi, van Leeuwen, & Douglas, 2007; Pedersen, Ascher, Monroe, & Prange, 1982; Theodosis, Montagnese, Rodriguez, Vincent, & Poulain, 1986)”
  • The seminal paper demonstrating the effect of oxytocin on maternal behavior also showed that vasopressin stimulates maternal behavior, but with a longer latency of action.

    “However, the seminal paper demonstrating the effect of OXT on maternal behavior also showed that AVP stimulates maternal behavior, but with a longer latency of action (132).”
  • Maternal behavior can be elicited through administration of oxytocin in virgin rats.

    “Maternal behavior can be elicited through administration of oxytocin in virgin rats (Pedersen et al., 1982);”

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.
