The Focus on Neuroscience box, "Dopamine Receptors and Obesity," discussed a study in which women each drank a rich chocolate shake and had her brain scanned with fMRI. Six months later, the women returned and had their brains scanned again after drinking a shake. What happened to the women who had gained weight in the six-month interval between the brain scans?

Women who gained weight showed a decrease in dopamine response to the milkshake during the second scan, suggesting that weight gain might be associated with reduced reward response from food, potentially leading to overeating to achieve the desired dopamine response.
