摘要：We have previously reported a study on brain activity detection in occipital region using a picotesla-scale MagnetoImpedance (MI) sensor. Based on past studies, the target of the present study was to review the performance of MI sensor on parietal region brain activity detection. Human brain magnetic field is extremely weak, in order to detect the faint magnetic field, we constructed an MI measurement system that can cancel out the background noise (e.g., geomagnetic field) instead of using a magnetic shielding. In this study, we recorded P300 brain waves of subjects, compared our results with our past studies and other EEG and MEG data reported previously. The results confirmed the reliability of our data and indicated that the MI sensor can be applied on brain activity detection.
