NEW ORLEANS, Nov. 10 - In new studies, scientists are discovering the neurobiological underpinnings of romantic love, trust, and even of self. New research also shows that a specific brain area - the amygdala - is involved in the process of understanding the intentions of others, in particular when lying is involved.
Using brain imaging, researchers Helen Fisher, Arthur Aron, Lucy Brown and colleagues find that feelings of intense romantic love are associated with specific activity in dopamine-rich brain regions associated with reward and motivation. Those study participants who expressed more romantic passion on a questionnaire showed more brain activity in these regions. Those in longer relationships showed more activation in emotion-related areas as well. And men and women tended to show some different brain responses. The researchers conclude that romantic love may be best classified as a motivation system or drive associated with a range of emotions. Further studies of intense, early stage romantic love may help to define how the brain encodes reward and memory.
