Something has to turn the exhilaration of a new partner into what can approach an obsession, and that something is the brain's nucleus accumbens, located slightly higher and farther forward than the ventral tegmental. Thrill signals that start in the lower brain are processed in the nucleus accumbens via not just dopamine but also serotonin and, importantly, oxytocin. If ever there was a substance designed to bind, it's oxytocin...
...fever--it's unsustainable over time. Fisher sees the dangers of maladaptive love in fMRI studies she's conducting of people who have been rejected by a lover and can't shake the pain. In these subjects, as with all people in love, there is activity in the caudate nucleus, but it's specifically in a part that's adjacent to a brain region associated with addiction. If the two areas indeed overlap, as Fisher suspects, that helps explain why telling a jilted lover that it's time to move on can be fruitless--as fruitless as admonishing a drunk...
