It's a question everyone has asked at least once: Am I in love, or just in lust?
A recent international study published in the Journal of Sexual Medicine hopes to answer that question by mapping out love and desire in the brain. "No one has ever put these two together to see the patterns of activation," says Jim Pfaus, co-author of the study. "We didn't know what to expect - the two could have ended up being completely separate. It turns out that love and desire activate specific but related areas in the brain."
Pfaus, along with colleagues in the United States and Switzerland, analyzed 20 different studies that examined the effects of sex and love on the body. The research recorded brain activity while subjects were engaged in tasks like viewing erotic photos, looking at pictures of their significant others, and viewing images of food and other pleasure triggers. By merging the data from all these studies, Pfaus and his team were able to create a complete map of love and desire in the brain.
They found that two structures of the brain - the insula and the striatum - are primarily responsible for the evolution of sexual desire into love. Love and sexual desire activate different areas of the striatum, which is located inside the forebrain. Lust triggers the parts of the brain that control pleasurable feelings, like those associated with sex and food, while love triggers the parts of the brain associated with habits.
Interestingly, the areas of the striatum that process love and desire are near to the area that is associated with drug addiction. "We assign different language to love and sexual desire and addiction," explains Pfaus. "But really, they're all being processed in a similar place. When we see this," he continues, "the idea of love at first sight probably isn't true. People are feeling desire."
In reality, love is actually a habit formed from sexual desire, as the desire is rewarded. "It works the same way in the brain as when people become addicted to drugs," Pfaus adds. The change that transforms desire into love is the bonding mechanism in relationships, the mechanism that is involved in monogamy and in connection in a variety of other relationships.
"This research speaks to evolution," says Pfaus. "And it could help understand addiction, love and other social neuroscience research."
