Hi could anyone explain the biological basis behind romantic love. What is the biological basis of falling in love?I know that serotonin and dopamine are secreted when we first fall in love. What happens after that as we move on to the more advanced stages of love. Why is it that after some time, we no longer feel the initial feelings of love. What is the biological basis behind it. And also why do we feel so heartbroken if we happen to fall out of love? What is the biological basis behind it?
Dopamine, norepinephrine, and serotonin are more commonly found during the attraction phase of a relationship.
All these chemicals stimulate the brain's pleasure center. But this stage only lasts 1.5 - 3 years . That's why 'we no longer feel the initial feelings of love'.
Oxytocin and vasopressin seemed to be more closely linked to long term bonding and relationships characterized by strong attachments .
Attachment makes relationships last for years and decades. It is based on commitment and mutual friendship. Oxytocin and vasopressin are at higher levels .
The neurological process involved in the perception of heartache is not known, but is thought to involve the anterior cingulate cortex of the brain, which during stress may overstimulate the vagus nerve causing pain, nausea or muscle tightness in the chest .
