The interpretation of the International Federation of Clinical Neurophysiology electroencephalography electrode array standards (2017) / 中华神经科杂志

ABSTRACT

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.
