Oxytocin affects meadow vole social preferences differently by brain region and duration
Bibliographic record
Abstract
Poster PS2.0055 International Congress of Neuroendocrinology. Toronto, Canada. July 2018. Poster abstract: Oxytocin is implicated in aspects of social behavior from maternal bonding to mating behavior. Oxytocin is also important for behaviors outside the reproductive context, including social recognition, aggression, and affiliation with same-sex peers. Meadow voles are seasonally social during the winter months, or short photoperiods in the lab. In short photoperiods they form selective preferences for familiar same-sex peers, and engage in some stranger-directed affiliative behavior. Oxytocin signaling modulates social behavior in female meadow voles. Early studies indicated that same-sex partner preferences are strengthened by chronic central oxytocin administration. However, acute administration of oxytocin into the lateral septum decreased partner preference. Acute administration of oxytocin to the central nucleus of the amygdala also led to a significant decrease in partner huddling, while acute central administration did not alter preferences. Site-specific administration to any of these regions did not affect total huddling time. Here I present results of these past and current studies of oxytocin together, as a way of building an integrated framework for understanding the effects of oxytocin across brain regions and time-scales. Further investigation into the influence of oxytocin administration location and timing will help shape our understanding of the role of oxytocin in behavior.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
