The role of oxytocin in plasticity, memory and attachment dynamics.

The peptide hormones oxytocin (OT) and arginine vasopressin (AVP) have been implicated in the regulation of mammalian social behavior. There is considerable evidence implicating both oxytocin and vasopressin in social recognition and social memory. This review explores their role in attachment dynamics. Oxytocin is one element in a complex network of interactions observed in natural phenomena ranging from molecular biology, etology, social behavior and human psychology.
