Don: I'm trying to write a poem to my sweetheart. Can you think of a good metaphor1 for love?

Yael: How about hunger or thirst?

D: I don't know about that. I was thinking something like love is a rose, except less cliché.

Y: You must be talking about a later stage of romantic love because that metaphor is entirely2 off target when it's very early love that we're talking about.

D: And hunger or thirst IS on target for early love? Are you saying that our need for love is as basic as our needs for food and water?

Y: Something like that. When we're craving3 things like food, water, or drugs, or anticipating getting them, two areas deep within the brain, the ventral tegmental area and caudate nucleus4, are active. A neurochemical called dopamine is released from the ventral tegmental area into the caudate nucleus. Neuroscientists have produced brain scan images of the brains of people falling in love, when they're feeling the passion of a very new relationship that has yet to become comfortable and secure. What they found is that the brain in love looks a lot like the brain craving or anticipating things like food or drugs. The same areas of the brain are active. Interestingly, this region is located in a different area of the brain from the region associated with determining physical attractiveness.

D: You mean that our brain makes a distinction between simply finding someone attractive and being mad about them, as they say?

Y: Yes. That these emotions activate5 completely different parts of the brain suggests that romantic love doesn't just feel different than sexual attraction, but that our brains register these as two different urges.
