We introduced a magneto-encephalographic (MEG) hyperscanning system to examine brain-to-brain interactions. We used two whole-head MEG systems placed in the same magnetically-shielded room. One is a 160-channel gradiometer system for an adult and the other is a 151-channel gradiometer system for a child. Moreover, we developed an audio-visual presentation system. From the result of assessment of delay in presentation, a parent-child interaction can be measured by this system in real time.
