Plus, oxytocin also calms the reactivity of the amygdala, the fear center of your
brain, and
strengthens its communication with
brain circuits that help you control emotions.

circuit that originally evolved to
strengthen the mother - infant bond during breastfeeding, and now uses this
brain circuitry to
strengthen the bond between couples as well.
