In the Western world we have for centuries concocted poems and stories and plays about the cycles of love, the way it morphs and changes over time, the way passion grabs us by our flung-back throats and then leaves us for something saner. If Dracula—the frail woman, the sensuality of submission—reflects how we understand the passion of early romance, the Flintstones reflects our experiences of long-term love: All is gravel and somewhat silly, the song so familiar you can’t stop singing it, and when you do, the emptiness is almost unbearable.
We have relied on stories to explain the complexities of love, tales of jealous gods and arrows. Now, however, these stories—so much a part of every civilization—may be changing as science steps in to explain what we have always felt to be myth, to be magic. For the first time, new research has begun to illuminate where love lies in the brain, the particulars of its chemical components.
