Nutrition affects brain structure and function throughout life. Nutritional scientists and practitioners are interested in gathering evidence clarifying which of the micro- or macronutrients may affect particular aspects of brain functioning at a given period of the life cycle and in identifying possible brain mechanisms underlying such effects. This article provides a primer on brain imaging techniques suitable for the assessment of the structure and function of the human brain, focusing on noninvasive techniques such as structural and functional magnetic resonance imaging, electroencephalography, and magnetoencephalography. The article concludes with a few suggestions regarding the choice of a particular imaging tool in observational studies and randomized controlled trials investigating nutritional effects on the human brain.
营养会影响大脑结构和功能的一生。营养科学家和从业者都有兴趣收集证据，阐明哪些微量营养素或宏量营养素可能会影响特定的大脑功能的特定方面在特定时期的生命周期，并确定可能的大脑机制的影响。本文提供了一个入门的脑成像技术，适用于评估人类大脑的结构和功能，重点介绍了非侵入性技术，如结构和功能磁共振成像、脑电图和脑磁图。文章最后提出了一些关于选择特定成像工具的建议，在观察性研究和随机对照试验中，研究营养对人脑的影响。
