The aim of this paper is to describe the patterns of functional magnetic resonance imaging activation produced by visual food stimuli in healthy participants, as well as in those with anorexia nervosa, bulimia nervosa, binge eating disorder and obesity. We conducted a systematic review of studies published in the last decade on normal and abnormal eating. This review suggested the existence of neural differences in response to the sight of food between healthy individuals, those with an eating disorder and obese subjects. Differences were identified in two brain circuits: (i) limbic and paralimbic areas associated with salience and reward processes and (ii) prefrontal areas supporting cognitive control processes.
本文旨在描述健康参与者以及神经性厌食症、神经性贪食症、暴食症和肥胖症患者对视觉食物刺激产生的功能磁共振成像激活模式。我们对过去十年中关于正常和异常进食的研究进行了系统综述。该综述表明，健康个体、饮食障碍患者和肥胖个体对食物的视觉反应存在神经差异。差异存在于两个大脑回路中：（i）与突显和奖励过程相关的边缘和边缘旁区域，以及（ii）支持认知控制过程的前额叶区域。
