Abstract

The aim of this study is to define the anatomical localization of corresponding brain function area during calculating. The activating modes in brainduring continuous silent calculating subtraction and repeated silent reading multiplication table were compared and investigated. Fourteen volunteersof right-handedness were enrolled in this experiment. The quite differenceof reaction modes in brain area during the two modes of calculation revealthat there are different processing pathways in brain during these two operating actions. During continuous silent calculating, the function area is localized on the posterior portion of superior and middle gyrus of frontal lobe and the lobule of posterior parietal lobe (P < 0.01, T = 5.41). It demonstrates that these function areas play an important role in the performance of calculation and working memory. Whereas the activating of visual cortex shows that even in mental arithmetic processing the brain action is having the aid of vision and visual space association.
