The hedonic component of eating is an underexplored topic within neuroscience, which is surprising given its importance for our survival and general well-being, as well as the obvious links to obesity and eating disorders. Based on findings from neuroimaging, this review gives an overview of the established principles, neural mechanisms and functional neuroanatomy of the primate and human brain processing systems involved in controlling eating. Four main processing principles underlying these processes are discussed: (1) motivation-independent discriminative processing of identity and intensity, (2) formation of learning-dependent multimodal sensory representations, (3) reward representations using mechanisms including selective satiation, and (4) representations of hedonic experience, monitoring/learning or direct behavioural change.
进食的享乐成分在神经科学领域是一个未被充分探索的主题，鉴于其对我们生存和总体幸福感的重要性，以及与肥胖和饮食失调的明显关联，这一点令人惊讶。基于神经影像学的研究结果，本综述概述了灵长类动物和人类大脑中参与控制进食的加工系统的既定原则、神经机制和功能神经解剖学。讨论了这些过程背后的四个主要加工原则：（1）与动机无关的对食物特性和强度的辨别加工；（2）形成依赖学习的多模态感觉表征；（3）利用包括选择性饱腹感在内的机制进行奖赏表征；（4）享乐体验的表征、监测/学习或直接行为改变。
