This paper reviews the effect of 50-60 Hz weak electric, magnetic and combined electric and magnetic field exposure on cognitive functions such as memory, attention, information processing and time perception, as determined by electroencephalographic methods and performance measures. Overall, laboratory studies that have investigated the acute effects of power frequency fields on cognitive functioning in humans are heterogeneous, in terms of both electric and magnetic field (EMF) exposure and the experimental design and measures used. Results are inconsistent and difficult to interpret with regard to functional relevance for possible health risks. Statistically significant differences between field and control exposure, when they are found, are small, subtle, transitory, without any clear dose-response relationship and difficult to reproduce. The human performance or event related potentials (ERPs) measures that might specifically be affected by EMF exposure, as well as a possible cerebral structure or function that could be more sensitive to EMF, cannot be better determined.
本文综述了通过脑电图方法和行为指标所确定的50 - 60赫兹弱电场、磁场以及电场和磁场联合暴露对认知功能（如记忆、注意力、信息处理和时间感知）的影响。总体而言，就电场和磁场（EMF）暴露以及所采用的实验设计和指标而言，调查工频场对人类认知功能急性影响的实验室研究存在异质性。关于对可能健康风险的功能相关性，结果并不一致且难以解释。当发现场暴露与对照暴露之间存在统计学显著差异时，这些差异很小、不明显、短暂，没有任何明确的剂量反应关系且难以重复。可能受到EMF暴露特异性影响的人类行为或事件相关电位（ERP）指标，以及可能对EMF更敏感的大脑结构或功能，目前尚无法更确切地确定。
