...elaborate ritual of dating is how this screening takes place. It's when that process pays off-when you finally feel you've found the right person-that the true-love thrill hits, and studies of the brain with functional magnetic resonance imagers (fMRIs) show why it feels so good. The earliest fMRIs of brains in love were taken in 2000, and they revealed that the sensation of romance is processed in three areas. The first is the ventral tegmental, a clump of tissue in the brain's lower regions, which is the body's central refinery for dopamine. Dopamine...
...Fisher and her colleagues have conducted recent fMRI scans of people who are not just in love but newly in love and have found that their ventral tegmental areas are working particularly hard. "This little factory near the base of the brain is sending dopamine to higher regions," she says. "It creates craving, motivation, goal-oriented behavior-and ecstasy...
...dopamine, the ventral tegmental couldn't do the love job on its own. Most people eventually do leave the poker game or the dinner table, after all. 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...
This is not the only study to have suggested that disbelief and moral outrage may be processed in the area of the brain that makes us go "Blechh." Sam Bowles, professor of human behavior at the Santa Fe Institute, describes research in which an unfair business deal produced a response in the same region. How did disgust get involved in the belief-and-disbelief business? Some think it started as a fairly straightforward adaptation to enable a suspicious taste, smell or appearance--like that of vermin--to trigger the impulse to eliminate the source. We may have then generalized that...
...Clinton's debate performance on Saturday, which the theater critics panned, actually served her well with voters and raised once more whether Democrats are looking for a fighter or a healer. ABC News brought in market researchers who hooked up voters with electrodes to monitor their brain activity. Her flash of anger when the boys ganged up played well with all of them; so did her humor, when she was asked why people don't like her: "Well, that hurts my feelings." But viewers really hated Obama's graceless barb when he told her, "You're likable enough...
