多模式监测在人脑功能研究中已经变得特别普遍。在这种背景下，功能近红外光谱（fNIRS）和脑电图（EEG）的联合同步测量越来越受到人们的关注。由于没有电光干扰，将这两种非侵入性脑活动记录过程结合起来非常简单。fNIRS和EEG都是头皮定位程序。fNIRS依靠光谱测量来估计脑血流动力学波动，而EEG通过被动电压评估来捕捉脑电活动的宏观时间动态。两种技术提供的“正交”神经生理学信息以及对神经血管耦合现象的日益关注进一步促进了它们的整合。本文介绍了这两种技术的原理和未来发展方向，并对这种灵活、低成本的神经成像方式组合的主要临床和非临床应用进行了评估。fNIRS-EEG系统利用了这两种技术在环境或实验环境和/或通常不适合其他神经成像方式（如功能磁共振成像、正电子发射断层扫描和脑磁图）的对象上进行的能力。fNIRS-EEG脑监测是一种有用的多模态脑电和血流动力学研究工具。
Multimodal monitoring has become particularly common in the study of human brain function. In this context, combined, synchronous measurements of functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG) are getting increased interest. Because of the absence of electro-optical interference, it is quite simple to integrate these two noninvasive recording procedures of brain activity. fNIRS and EEG are both scalp-located procedures. fNIRS estimates brain hemodynamic fluctuations relying on spectroscopic measurements, whereas EEG captures the macroscopic temporal dynamics of brain electrical activity through passive voltages evaluations. The “orthogonal” neurophysiological information provided by the two technologies and the increasing interest in the neurovascular coupling phenomenon further encourage their integration. This review provides, together with an introduction regarding the principles and future directions of the two technologies, an evaluation of major clinical and nonclinical applications of this flexible, low-cost combination of neuroimaging modalities. fNIRS–EEG systems exploit the ability of the two technologies to be conducted in an environment or experimental setting and/or on subjects that are generally not suited for other neuroimaging modalities, such as functional magnetic resonance imaging, positron emission tomography, and magnetoencephalography. fNIRS–EEG brain monitoring settles itself as a useful multimodal tool for brain electrical and hemodynamic activity investigation.
