Pitocin · the "bonding hormone"

Oxytocin is a 9-amino-acid neuropeptide produced in the hypothalamus and released by the posterior pituitary. Beyond its classic roles in parturition and lactation, research demonstrates effects on social bonding, trust, empathy, fear extinction, and autism spectrum disorder. Intranasal oxytocin research has produced mixed results in clinical trials, but it remains one of the most studied peptides in social neuroscience.
