Oxytocin is the hormone neurotransmitter of social bonding. It is most widely known for its involvement in childbirth and breastfeeding, where it plays important roles in both lactation and bonding. Oxytocin also facilitates relationships of trust and attachment between people and is generally associated with prosocial behaviors, also acting as a mild antidepressant and reducing fear. It is a lovely neurotransmitter all around.
