The role of oxytocin in shaping complex social behaviours: possible interactions with other neuromodulators.

This review explores the role of oxytocin in the mediation of select social behaviours, with particular emphasis on female rodents. These behaviours include social recognition, social learning, pathogen detection and avoidance, and maternal care. Specific brain regions where oxytocin has been shown to directly mediate various aspects of these social behaviours, as well as other proposed regions, are discussed. Possible interactions between oxytocin and other regulatory systems, in particular that of oestrogens and dopamine, in the modulation of social behaviour are considered. Similarities and differences between males and females are highlighted. This article is part of the theme issue 'Interplays between oxytocin and other neuromodulators in shaping complex social behaviours'.
