Stephen is not in Vegas. He's watching a video monitor in Paul Glimcher's neural-science lab at New York University. And his head is plugged into a high-powered Siemens functional magnetic resonance imaging scanner (fMRI). His name is not actually Stephen; he's a composite research subject. Glimcher is at the frontal lobe of an intriguing network of brain researchers and economists who are using advanced medical technology to try to figure out why people make the decisions they do--what brand of cereal, which mutual fund--and what part of the brain tells them...
...Jack,? she ordered. ?Give me the truck.? Jack handed it over. The three of them were all a-giggle as they waited their turn at the scanner; it might as well have been C.S.

...invited him or her to participate. We acquired two photographs: one of the beloved and one of an emotionally neutral individual. Generally the latter was someone the subject had known casually in high school or college. Then we set a date to put each subject into the brain scanner...
...procedure was simple but not easy. First Mashek and I made the participant as comfortable as possible in the scanner--a large, horizontal, cylindrical, cream-colored plastic tube that is open at both ends and extends from above the head to about the waist. After taking preliminary scans to establish basic brain anatomy, the 12-min. experiment started. First the subject looked at the photograph of the beloved on the screen for 30 sec. as the scanner recorded blood flow in various brain regions. Next the subject was shown a large number and asked to count backward...
...discovered this in a curious way. Before our subjects entered the brain scanner, we asked each to fill out several questionnaires, including a survey designed by psychologist Elaine Hatfield and sociologist Susan Sprecher called the Passionate Love Scale (see box). We wanted to compare the brain activity of each subject to what that subject reported on a questionnaire. We found a positive correlation: those who scored higher on the Passionate Love Scale also showed more activity in a specific region of the caudate...
