Oxytocin induction of short-latency maternal behavior in nulliparous, estrogen-primed female rats

FAHRBACH, S·1984·Hormones and Behavior

Abstract

This study was designed to test whether intracerebroventricular (icv) administration of oxytocin can shorten the latency of estrogen-treated virgin rats to respond to foster pups with maternal care. A secondary goal was a description of the behavioral effects of icv oxytocin in rats. Forty-eight hours before pup presentation female rats (Sprague-Dawley strain, obtained from Zivic-Miller Laboratories, Inc.) with chronic lateral ventricle cannulae were ovariectomized and treated with 100 micrograms/kg body wt estradiol benzoate (EB). Immediately before pup presentation either 400 ng oxytocin or the normal saline vehicle was infused. A second control group of noncannulated animals received the same surgery, EB treatment, and behavior tests without any icv infusion. Maternal behavior was scored on a scale from 0 to 5, one point each being given for licking pups, carrying pups, grouping pups, crouching over pups, and nest building. At the end of 1 hr of pup exposure 65% of the oxytocin-infused animals received scores of 4 or 5, while only 25% of the control animals attained these scores. Maternal behavior appeared as a unit in both spontaneously maternal and oxytocin-treated animals, with fewer than 10% in either group receiving scores of 1, 2, or 3. The oxytocin group also spent significantly more time grooming. In a second experiment in which oxytocin or normal saline was administered icv to oil-treated animals, this grooming effect was shown to be estrogen independent while the induction of maternal behavior required prior treatment with estrogen. Finally, a slight, transient hyperthermic effect of oxytocin on body temperature was observed in this test paradigm. These data suggest a role for oxytocin, acting with estrogen, in the onset of maternal behavior in rats.

  • The transition from juvenile to adult patterns of alloparental behavior in female prairie voles does not appear to be related to changes in sex hormones.

    “The transition from juvenile to adult patterns of alloparental behavior in females does not appear to be related to changes in sex hormones [40].”
  • As female prairie voles reach puberty, only about 50% will spontaneously retrieve, lick/groom, and hover over pups presented to them, with the remainder either ignoring or attacking pups.

    “However, as females reach puberty, only about 50% of the females will spontaneously retrieve, lick/groom, and hover over pups presented to them, with the remainder of the females either ignoring or attacking pups [38-40].”

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.
