PD Katie Yoest and lab members published a paper in the journal Hormones & Behavior on the “Development of social recognition ability in female rats: Effect of pubertal ovarian hormones“. In this paper, Katie shows that juvenile female rats do not show adult rat-typical patterns of social recognition in the social discrimination test while juvenile male rats do. This is an important observation because in addition to sex, age seems a variable taken into account when using behavioral tests originally developed for adult male rats. Katie further shows that juvenile female rats begin to show successful social discrimination at adolescence age and that this depends on pubertal ovarian hormones. However, estradiol given to pre-pubertally ovariectomized adult female rats does not restore social discrimination, suggesting a more complex involvement of multiple ovarian hormones in the adolescent onset of social discrimination in female rats. Notably, juvenile female rats showed social recognition in the habituation-dishabituation test, suggesting intact social recognition at this age. Overall, findings indicate to be aware that a widely used behavioral test might work differently when changing sex, age, and potentially other factors of the experimental organism.
