Abstract (in Japanese) (See Japanese page) 
(in English) This study investigates the feasibility of magnetoencephalography (MEG) hyperscanning with optically pumped magnetometers (OPM). Brain activities during communication showed differences in alpha-band normalized amplitudes between the Natural and Patterned conditions, supporting OPM-MEG's potential to detect subtle neural activity changes, comparable to traditional MEG.
