The Anatomy of Love

February is the month of love. When you are attracted to another person, your brain releases dopamine, your serotonin levels increase, and oxytocin is produced.

These hormones make you feel a stream of positive emotions. The dopamine hormone is produced at the hypothalamus and the substantia nigra and ventral tegmental of the midbrain (mesenchephalon).

Serotonin is manufactured in the neurons originating in the raphe nuclei located in the midline of the brainstem but also 90% of our serotonin supply is found in the digestive tract and blood platelets.

Oxytocin is produced in the hypothalamus and is secreted into the bloodstream by the posterior pituitary gland (hypophysis). Oxytocin is a hormone that acts on organs such as the breast and uterus, controlling key functions of the reproductive system, including childbirth and lactation, and aspects of human behavior feeling in love.
