“…In an experiment published as a chapter in a 2006 book, “Evolutionary Cognitive Neuroscience,” Fisher found 17 people who were in relationships for an average of seven months. She knew they were in love from their answers to what researchers call the Passionate Love Scale. They all said they’d feel deep despair if their lover left, and they yearned to know all there was to know about the loved one.

She put these lovesick, enraptured people in an fMRI to see what areas of their brains got active when they saw a photograph of their beloved ones.

“We found some remarkable things,” she said. “We saw activity in the ventral tegmental area and other regions of the brain’s reward system associated with motivation, elation and focused attention.” It’s the same part of the brain that presumably is active when a smoker reaches for a cigarette or when gamblers think they’re going to win the lottery. No wonder it’s as hard to say no to the feeling of romantic arousal as it would be to say no to a windfall in the millions. The brain has seen what it wants, and it’s going to get it.

“At that point, you really wouldn’t notice if he had three heads,” Fisher says. “Or you’d notice, but you’d choose to overlook it.”

Other studies also suggest that the brain in the first throes of love is much like a brain on drugs.

Lucy Brown, professor of neuroscience at the Albert Einstein College of Medicine, has also taken fMRI images of people in the early days of a new love. In a study reported in the July 2005, Journal of Neurophysiology, she too found key activity in the ventral tegmental area. “That’s the area that’s also active when a cocaine addict gets an IV injection of cocaine,” Brown says. “It’s not a craving. It’s a high.”

You see someone, you click, and you’re euphoric. And in response, your ventral tegmental area uses chemical messengers such as dopamine, serotonin and oxytocin to send signals racing to a part of the brain called the nucleus accumbens with the good news, telling it to start craving.

“The other person becomes a goal in your life,” Brown says. He or she becomes a goal you might die without and would pack up and move across the country for. That one person begins to stand out as the one and only…”
