The neurohypophysial peptide oxytocin (OT) and OT-like hormones facilitate reproduction in
all vertebrates at several levels. The major site of OT gene expression is the magnocellular …

The hypothalamic neuropeptide oxytocin has drawn the attention of scientists for more than
a century. The understanding of the function of oxytocin has expanded dramatically over the …

Oxytocin (Oxt) is a nonapeptide hormone best known for its role in lactation and parturition.
Since 1906 when its uterine-contracting properties were described until 50 years later when …

In the mammalian peripartum period, the activity of both the brain oxytocin and vasopressin
system is elevated as part of the physiological adaptations occurring in the mother. This is …

The oxytocinergic system is critically involved in the regulation of maternal behavior, which
includes maternal aggression. Because aggression has been linked to anxiety, we …

Male behavioral responses to offspring range from avoidance to infanticide to nurturing care.
If this book were focussed on parental care among nonmammalian vertebrates, most of the …

The peptide hormones oxytocin and vasopressin have been implicated in a range of
mammalian social behaviors including maternal care, pair bonding and affiliation. Oxytocin …

The most significant social behaviour of the lactating mother is maternal behaviour, which
comprises maternal care and maternal aggression (MA). The latter is a protective behaviour …

Humans present a behavioural paradox: they are peaceful in many circumstances, but they
are also violent and kill conspecifics at high rates. We describe a social evolutionary theory …

Although behavioral neuroendocrinologists often discuss “sociality” as a unitary variable, the
term encompasses a wide diversity of behaviors that do not evolve in a linked fashion across …
