Neonatal manipulation of oxytocin influences the partner preference in mandarin voles (Microtus mandarinus)
Abstract
Neonatal manipulation of oxytocin (OT) has long-term effects on behavior and physiology. The objective of this research was to determine if neonatal exposure to OT can affect partner preferences and to characterize the mechanisms underlying social behavior such as neural activities of relevant brain regions in socially monogamous mandarin voles (Microtus mandarinus). After receiving a subcutaneous injection of isotonic saline (SAL) or OT within 24h of birth, mandarin vole at 60 days of age was paired with an unfamiliar opposite sex for 24h, followed immediately by an examination of their partner preference and 30 days later by the second examination of their partner preference and Fos expression in some brain regions. The results indicated that (1) while 24h cohabitation was insufficient for both female and male SAL-treated mandarin voles to form partner preference, neonatal exposure to OT significantly facilitate female, but not male mandarin voles to form partner preference within 24h of cohabitation; (2) the maintenance of partner preference in females was suppressed by neonatal OT treatment, while neonatal OT-treated males showed significant partner preference as neonatal SAL-treated males and females; in addition, the tendency of aggression to the strangers was impaired in both females and males, and neonatal OT-treated males showed significantly higher mounting behavior to the partner; (3) in comparison with saline-treated females, OT-treated females showed a significan…

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.
