Individuals that are right handed, and not claustrophobic were recruited. This same group was used for the smoking-group and refrain from smoking was evaluated by CO2 evaluation. To be classified as smokers, they had to report smoking 3-10 cigarettes daily for at least the last year and have a carbon monoxide reading of CO >10 ppm.
Healthy individuals meeting the inclusion criteria who claim to not smoke. This is confirmed w/ CO testing.
- fMRI w/ taste and smell stimuli [ Time Frame: 1-2 hours ]Subjects will be scanned on a 3T Trio magnet while tasting and smelling various food and non-food substances. Our primary outcome measure will be differential brain responses to taste and smell stimuli as a function of group (smokers vs. nonsmokers).
