Intense energy, elation, mood swings, emotional dependence, separation anxiety, possessiveness, physical reactions including a pounding heart and shortness of breath, and craving, Fisher reports, are all central to this feeling. As Fisher says, "Someone is camping in your head." Fisher and her colleagues studied the brain circuitry of romantic love by f MRI-scanning the brains of forty-nine men and women: seventeen who had just fallen madly in love, fifteen who had just been dumped, and seventeen who reported that they were still in love after an average of twenty-one years of marriage.One of her central ideas is that romantic love is a drive that is stronger than the sex drive.Prior to Rutgers University, she was a research associate at the American Museum of Natural History in New York City. She is now the most referenced scholar in the love research community.
She was one of the main speakers at the 20 TED conference. She appears in the 2014 documentary film about heart-break and loneliness, entitled Sleepless in New York.Love can start with any of these three feelings, Fisher maintains.
