目的：为了验证这一假设，情绪化进食者在对食物摄入和预期食物摄入的反应中表现出比非情绪化进食者更大的神经激活，以及这些差异是否在消极与中性情绪状态下被放大。方法：女性情绪性进食者和非情绪性进食者（N=21）接受功能性磁共振成像（fMRI）检查在接受和预期接受巧克力奶昔和无味对照溶液期间，同时处于消极和中性情绪。结果：情绪化进食者的海马旁回和前扣带回（ACC）在预期收到奶昔时表现出更大的激活，苍白球、丘脑、和ACC的响应接收奶昔在一个相对于中性情绪的负面。相反，nonemotional eaters表现出减少激活的奖励区域在一个消极的相对于一个中立的mood.Discussion：结果表明，情绪化饮食是增加预期和完善的食物奖励，但只有在消极的情绪。(C)出版社：Wiley Periodicals，Inc.
Objective: To test the hypothesis that emotional eaters show greater neural activation in response to food intake and anticipated food intake than nonemotional eaters and whether these differences are amplified during a negative versus neutral mood state.Method: Female emotional eaters and nonemotional eaters (N=21) underwent functional magnetic resonance imaging (fMRI) during receipt and anticipated receipt of chocolate milkshake and a tasteless control solution while in a negative and neutral mood.Results: Emotional eaters showed greater activation in the parahippocampal gyrus and anterior cingulate (ACC) in response to anticipated receipt of milkshake and greater activation in the pallidum, thalamus, and ACC in response to receipt of milkshake during a negative relative to a neutral mood. in contrast, nonemotional eaters showed decreased activation in reward regions during a negative versus a neutral mood.Discussion: Results suggest that emotional eating is related to increased anticipatory and consummatory food reward, but only during negative mood.
