The Focus on Neuroscience Box, "Dopamine Receptors and Obesity," Described

The Focus on Neuroscience box, "Dopamine Receptors and Obesity," described a PET scan study comparing normal-weight and obese individuals. The findings of that study suggest that:

A) obesity causes the brain to increase the number of dopamine receptors and dopamine production.
B) obese individuals might engage in compulsive or binge eating to inhibit the production of dopamine by the brain's reward system.
C) individuals who have more dopamine receptors in their brains are more likely to overeat and become obese.
D) obese individuals might engage in compulsive or binge eating to stimulate the brain's reward system.
