Pair bond quality influences social conditioned place preference expression, passive coping behavior, and central oxytocin receptor expression following partner loss in male prairie voles.

The dissolving of social bonds is disruptive and leads to increased stress responsivity and a strong desire for reunion. The oxytocin (OXT) system is critical for the formation of social attachments, such as pair bonds, and is also involved in social recognition, social memory, and social vigilance. Therefore, long-term changes in the OXT system resulting from cohabitation and pair bonding may contribute to reunion-seeking behavior.

Delivery by cesarean section leads to heavier adult bodyweight in prairie voles (Microtus ochrogaster).

Delivery by cesarean section now makes up 32.1 % of all births in the United States. Meta-analyses have estimated that delivery by cesarean section is associated with a > 50 % increased risk for childhood obesity by 5 years of age.

Automated behavioral scoring: Do we even need humans?

The development of automated behavior scoring technology has been a tremendous boon to the study of social behavior. However, completely outsourcing behavioral analysis to a computer runs the risk of overlooking important nuances, and researchers risk distancing themselves from their very object of study. Here, I make the case that while automating analysis has been valuable, and overautomating analysis is risky, more effort should be spent automating the collection of behavioral data.
