ABSTRACT
This study was conducted to analyze the impact on human's left and right brain by mental calculation based on principal components analysis (PCA). Electroencephalogram (EEG) data were collected from twenty-one people before and during mental calculation. In each subject, we first calculated the PCA load of maximum principal component of the theta wave in four brain electrodes of the forehead, then we analyzed the relationship between mental calculating event and each brain electrode. From closing eye to relaxing event and to performing mental calculation event, it was shown that the weight of left head decreased and the weight of right head increased. These results indicate that mental calculation increases the workload on the right forehead, and on the right side of head obviously.
