标准化的EEG电极位置对于临床应用和研究都是必不可少的。本指南的目的是更新和扩展EEG头皮电极的统一命名和标准化定位。电极位置基于颅骨解剖标志的20%和10%的标准化测量。然而，标准记录不包括前颞叶和基底颞叶，这是最常见的癫痫活动来源。在这里，我们提出了一个包括下颞链在内的25个电极的基本阵列，它应该用于所有标准的临床记录。基本数组中的命名法与10-10系统一致。高密度头皮脑电图阵列（64-256个电极）允许源成像达到亚叶级精度。必要时应要求进行这项补充检查，例如，在阴性标准脑电图中寻找致痫性活动或进行术前评估。在不久的将来，需要定义超过10-10系统的高密度电极阵列的命名法，以便跨中心进行比较和标准化记录。与“小脑袋需要更少电极”的既定观念相反，由于小脑袋的厚度和空间混叠的风险，幼儿至少应该与成人使用一样多的电极。(C) 2017国际临床神经生理学联合会。爱思唯尔爱尔兰有限公司出版。版权所有。
Standardized EEG electrode positions are essential for both clinical applications and research. The aim of this guideline is to update and expand the unifying nomenclature and standardized positioning for EEG scalp electrodes. Electrode positions were based on 20% and 10% of standardized measurements from anatomical landmarks on the skull. However, standard recordings do not cover the anterior and basal temporal lobes, which is the most frequent source of epileptogenic activity. Here, we propose a basic array of 25 electrodes including the inferior temporal chain, which should be used for all standard clinical recordings. The nomenclature in the basic array is consistent with the 10-10-system. High-density scalp EEG arrays (64-256 electrodes) allow source imaging with even sub-lobar precision. This supplementary exam should be requested whenever necessary, e.g. search for epileptogenic activity in negative standard EEG or for presurgical evaluation. In the near future, nomenclature for high density electrodes arrays beyond the 10-10 system needs to be defined, to allow comparison and standardized recordings across centers. Contrary to the established belief that smaller heads needs less electrodes, in young children at least as many electrodes as in adults should be applied due to smaller skull thickness and the risk of spatial aliasing.
