国际临床神经电生理联盟脑电图电极安放标准指南（2017）解读

The interpretation of the International Federation of Clinical Neurophysiology electroencephalography electrode array standards （2017）

脑电图电极位置的标准化放置对临床应用和研究至关重要.国际临床神经电生理联盟本次发布指南目的是更新和扩大脑电图头皮电极的统一命名和标准位置.10-20系统标准记录不包括颞叶前部和底部,此次指南提出了包括颞叶下部导联的25个电极排列标准,应用于临床作为标准记录.与现有观点不同,该指南建议儿童电极数量应至少与成人一样.高密度的头皮脑电图（64-256电极）可以使电来源定位精度达到亚脑叶.在不久的将来,甚至会有比10-10更为精密的系统出现.因此,更高密度的电极排列需要命名,以方便将来在不同中心进行标准化记录及脑电图的比较分析.

Standardized electroencephalography （EEG） electrode positions are essential for both clinical applications and research.The aim of the International Federation of Clinical Neurophysiology （IFCN） guideline is to update and expand the unifying nomenclature and standardized positioning for EEG scalp electrodes.Twenty percent and ten percent standard recordings do not cover the anterior and basal temporal lobes.Here,IFCN proposes a basic array of 25 electrodes including the inferior temporal chain,which should be used for all standard clinical recordings.Contrary to the established belief,the guideline suggests at least as many electrodes in young children as in adults.High-density scalp EEG arrays （64-256 electrodes） allow source imaging with even sub-lobar precision.In the future,nomenclature for high density electrodes arrays beyond the 10-10 system needs to be defined,to allow comparison and standardized recordings across centers.
