Montages are logical, orderly arrangements of electroencephalographic derivations or channels that are created to display activity over the entire head and to provide lateralizing and localizing information. Most often, bipolar and referential montages are used for routine electroencephalographic recordings. Common average and Laplacian montages can also be helpful in some situations. Because each type of montage has certain strengths and limitations, the ACNS guidelines recommend the use of multiple classes of montages for each electroencephalographic recording. A variety of factors need to be considered for localization by scalp electroencephalogram, but in clinical practice, a three-step approach can be used to localize an interictal epileptiform discharge by visual inspection using a standard set of scalp electrodes and conventional montages. The ACNS guideline provides a number of standard and suggested montages, but, depending on the clinical situation, additional montages can be designed using the electrodes within the 10-20 system or by placing additional electrodes.
叠加是对脑电描记图或通道进行逻辑有序的排列，用于显示整个头部的活动，并提供定位和定位信息。最常用的是双极和参考叠加，用于常规脑电图记录。在某些情况下，平均叠加和拉普拉斯叠加也很有帮助。由于每种类型的叠加都有一定的优势和局限性，ACNS 指南建议在每次脑电图记录中使用多种类型的叠加。头皮脑电图定位需要考虑多种因素，但在临床实践中，可以使用三步法通过使用标准的头皮电极和常规叠加来目视检查定位发作间期癫痫样放电。ACNS 指南提供了许多标准和建议的叠加，但根据临床情况，也可以使用 10-20 系统内的电极或放置额外的电极来设计其他叠加。
