<h3>
what is pair bonding?</h3>
Pair bonding is an evolutionary feature that may be important for reproduction as well as individual and species survival.
The proximate processes underlying many types of good social behaviours, such as pair bonding and maternal-infant behaviour, are shared by brain and endocrine systems.
The brain systems that rely on peptides, such as oxytocin, vasopressin, opioids, CRH, and associated hormones, are at the heart of pair bonding.
Neuropeptides also help to integrate the autonomic and endocrine effects of pleasant social encounters with behavioural states that promote social bond creation and maintenance.
