New recommendations of the IFCN: From scalp EEG to electrical brain imaging
Résumé
The importance of a standardized electrode placement (1) based on specific measurements of skull landmarks, (2) labeled according to a universal designation, and (3) offering adequate coverage of all parts of the head, was proposed by Dr. Jasper a few years after the first scalp EEG recordings and readily adopted by the Second International EEG Congress (Second International EEG congress, 1950). The 10–20 electrode system was born (Klem et al., 1999)! This electrode placement system was so clinically and physiologically relevant that it has been used without any significant change ever since.
