Hyperscanning MEG for understanding mother-child cerebral interactions

The underlying neural mechanism for parent-child interactions has not yet been revealed. 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, this system enabled a parent-child interaction in real time.
