Oxytocin
Oxytocin
Overview
Oxytocin is a nine-amino acid neuropeptide hormone produced in the hypothalamus. Often called the "love hormone" or "bonding hormone," it plays crucial roles in social bonding, sexual reproduction, childbirth, and emotional regulation. Intranasal oxytocin is studied for anxiety, autism spectrum disorders, and social cognition.
Mechanism of Action
Oxytocin acts on oxytocin receptors throughout the central nervous system and peripheral tissues. In the brain, it modulates amygdala activity (reducing fear responses), enhances social reward signaling in the ventral tegmental area, and promotes prosocial behavior. It reduces cortisol and HPA axis reactivity, providing anxiolytic effects. Peripherally, it stimulates uterine contractions and milk ejection.
