Neurochemistry

Oxytocin, called the hormone of love, is found in the hypothalamus of the brain and is associated with the ability to maintain healthy interpersonal relationships as well as physiological changes during reproduction. These changes include stimulation of the mammary glands to release milk, and assists in contracting the uterus during the final stages of childbirth. Oxytocin may also be the biological reason why mothers feel a need to cuddle and protect young. Some studies have indicated that women who experience strong positive emotions also have an increase in oxytocin release. Vasopressin, also called antidiuretic hormorne (ADH), is another hormone found in the Hypothalamus. Vasopressin is responsible for regulating blood volume and salt concentration. Oxytocin and vasopressin are also involved in parenting habits as they contribute to feelings of protection and evoke spending time raising young.
