['Eating behavior in humans is influenced by variables other than just hunger-satiety including cognitive restraint, emotional distress, and sensitivity to food stimuli. We investigate the role of dopamine (DA), a neurotransmitter involved with food motivation, in these variables.', 'We used the Dutch Eating Behavior Questionnaire (DEBQ) to measure Restraint, Emotionality, and Externality in 10 subjects. We correlated DEBQ scores with brain DA levels. Positron emission tomography and [(11)C]raclopride uptake were used to measure baseline D(2) receptors (neutral stimulation) and to assess changes in extracellular DA to food stimulation (display of food).', 'Restraint was correlated with DA changes with food stimulation (higher restraint, greater responsivity), emotionality was negatively correlated with baseline D(2) receptors (higher emotionality, lower D(2) receptors), whereas externality was not. These correlations were significant in the dorsal but not in the ventral striatum.'] Is brain dopamine associated with eating behaviors in humans?
