The anterior temporal electrode and the ten-twenty system

At the Colloquium on Teaching Methods in Electroencephalography of the American EEG Society ( 1959), a strong plea was made for all EEG laboratories to give up their individually devised numbering systems and electrode placements and to adopt a common language and common system, namely, the 10-20 electrode system proposed by the International Federation (Jasper 1958).

Abstract

Multi-modal fusion combines multiple modal information to overcome the limitation of incomplete information expressed by a single modality, so as to realize the complementarity of modal information and enhance feature representation. Multi-modal medical signal fusion algorithm and extraction equipment play an important role in improving the recognition accuracy of brain diseases. This paper compared the existing data fusion methods and explored the fusion research of multi-modal bioelectrical signals, including: (1) the challenges and shortcomings in the signal acquisition phase are explored from the biological signal acquisition equipment and scene settings; (2) five multi-modal fusion forms are analyzed; (3) the fusion methods and evaluation indexes are briefly reviewed; (4) the research status and challenges of multi-modal fusion in the field of spatial cognitive impairment and biometrics are explored; (5) the advantages and challenges of multi-modal fusion are described. The conclusion of this review is that the research of multimodal medical signal fusion is in the initial stage, and some studies have proved that multi-modal fusion is meaningful for medical research. However, the fusion algorithm and fusion strategy need to be improved. While learning the relatively perfect image fusion algorithm, we need to develop the fusion algorithm and fusion strategy that is suitable for medical signal and strengthen its feasibility in clinical application.
