Abstract

Naturally occurring variations in maternal licking/grooming influence neural development and are transmitted from mother to female offspring. We found that the induction of maternal behavior in virgin females through constant exposure to pups (pup sensitization) was significantly shorter in the offspring of High compared with Low licking/grooming mothers, suggesting differences in maternal responsivity. In randomly selected females screened for individual differences in maternal responsivity and subsequently mated, there was a significant and negative correlation (r = -0.73) between the latency to exhibit maternal behavior in the pup sensitization paradigm and the frequency of pup licking/grooming during lactation. Females that were more maternally responsive to pups and that showed increased levels of pup licking/grooming also showed significantly higher oxytocin receptor levels in the medial preoptic area, the lateral septum, the central nucleus (n.) of the amygdala, the paraventricular n. of the hypothalamus, and the bed n. of the stria terminalis. Intracerebroventricular administration of an oxytocin receptor antagonist to mothers on postpartum day 3 completely eliminated the differences in pup licking/grooming, suggesting that differences in oxytocin receptor levels are functionally related to maternal behavior. Finally, estrogen treatment of virgin females significantly increased oxytocin receptor binding in the medial preoptic area and lateral septum of female offspring of High, but not Low, licking/grooming mothers. These findings suggest that maternal licking/grooming influences the development of estrogen sensitivity in brain regions that regulate maternal behavior, providing a potential mechanism for the intergenerational transmission of individual differences in maternal behavior.

  • In mammals, more touch and contact increased oxytocin receptor density.

    “research in mammals showed that more touch and contact increased OT receptor density (Champagne et al., 2001).”

    From Oxytocin during the initial stages of romantic attachment: Relations to couples’ interactive reciprocity (2012) · cites this paper as Champagne et al., 2001

    The Results report that rat mothers with more pup licking/grooming had higher oxytocin receptor binding in several brain regions, but found no group difference in time spent in physical contact with pups. The Discussion describes an association and suggests that receptor differences may help drive licking/grooming; it does not show that more touch or contact caused receptor density to increase.

  • The oxytocinergic system involved in caregiving behavior also enhances social awareness.

    “recent evidence suggests that the oxytocinergic system that is involved in caregiving behavior (Bartels & Zeki, 2004; Champagne, Diorio, Sharma, & Meaney, 2001) also enhances social awareness.”

  • Maternal licking and grooming (LG), a form of tactile stimulation and affiliative care, is related to oxytocin receptor levels such that mothers who demonstrated higher LG have significantly higher receptor oxytocin levels.

    “Specifically, maternal licking and grooming (LG), a form of tactile stimulation and affiliative care, is related to oxytocin receptor levels such that mothers who demonstrated higher LG have significantly higher receptor oxytocin levels.”

  • OTKO mice housed in a social semi-natural environment are significantly more likely to display infanticidal behavior than wild-type mice in the same environment.

    “In a separate study, OTKO mice housed in a social semi-natural environment were significantly more likely to display infanticidal behavior than wild-type mice in the same environment [20].”

    From Oxytocin and the Neural Mechanisms Regulating Social Cognition and Affiliative Behavior (2009) · cites this paper as [20]

    The Materials and Methods (page unavailable) identify the animals as Long–Evans rats, and the Results concern maternal licking/grooming and oxytocin receptor antagonism. Searches for OTKO mice, semi-natural housing, and infanticide found no passage addressing the claimed comparison with wild-type mice. (LLM, conf=0.78)

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.
