Helen Fisher in her TED talk as posted on this site,
reveals that anti-depressents raise the serotonin levels in the brain while lowering the dopamine levels. Dopamine is responsible for romantic love which leads to secure attachments and deep relationships. Without dopamine, we stand the chance of living in a loveless society!.
What is strikingly frightening is the rates at which anti-depressents are being prescribed in western society. Anti-depressents can be useful in short term applications, but the implications for developing a heartless society in part through the overly prescribed “psyche” medications is alarming.
Helen Fisher reports on research she conducted on people in love and discovered there are three parts of the brain that get activated. The first has to do with lust, the next on romance, and the last with attachment. Ideally all three are activated in one relationship, but this is not always the case. A choice can be made to focus on one person integrating all three brain states to support an abiding, fully engaged relationship.
