Oxytocin Signaling in the Lateral Septum Prevents Social Fear during Lactation.

Oxytocin (OXT)-mediated behavioral responses to social and stressful cues have extensively been studied in male rodents. Here, we investigated the capacity of brain OXT receptor (OXTR) signaling in the lateral septum (LS) to prevent social fear expression in female mice using the social-fear-conditioning paradigm. Utilizing the activated OXT system during lactation, we show that lactating mice did not express fear 24 hr after social fear conditioning.

Salivary oxytocin concentrations in response to running, sexual self-stimulation, breastfeeding and the TSST: The Regensburg Oxytocin Challenge (ROC) study.

Intranasal oxytocin (OXT) application is emerging as a potential treatment for socio-emotional disorders associated with abnormalities in OXT system (re-) activity. The crucial identification of patients with such abnormalities could be streamlined by the assessment of basal and stimulus-induced OXT concentrations in saliva, using a simple, stress-free sampling procedure (i.e.
