Neuropeptides and the Development of Social Behaviors


This chapter provides an overview of the role of two mammalian neuropeptide hormones, oxytocin (OT) and arginine vasopressin (AVP), in the development and expression of social behaviors, including selective behaviors that are indicative of social bonds. It begins by giving a general background on social behavior in monogamous species, as well as the previously studied physiological and behavioral effects of OT and vasopressin. This is followed by a description of animal studies describing the role of OT and AVP during development. It then discusses current knowledge of possible developmental actions of OT and AVP, especially as these may be related to psychopathologies in later life.
