CSP-based EEG analysis on dissociated brain organization for single-digit addition and multiplication

Abstract

This paper presents results of the common spatial pattern (CSP) based electroencephalogram (EEG) analysis on dissociated brain organization for single-digit addition and multiplication. Alpha band EEG oscillations, which have been corroborated to be modulated by arithmetic strategies, are employed for feature extraction based on CSP. Experimental results have confirmed the dissociation between single-digit addition and multiplication. It is indicated that the dissociation originates from different cortical areas across subjects, such as IPS, parieto-occipital, and fronto-parietal regions.
