Dual-MEG Hyperscanning Facilities

MEGIN's Facility is Located at Tsinghua University

MEGIN has established a side-by-side dual-MEG hyperscanning facility at Tsinghua University in Beijing. The innovation features two TRIUX neo whole-head magnetoencephalography systems housed in adjacent magnetically shielded rooms and linked through a custom integration layer developed by Aalto University. The device enables simultaneous, millisecond-synchronized brain recording from two interacting participants during natural conversation, cooperation, and play.

MEGIN's configuration overcomes the limitations of previous MEG-based hyperscanning approaches, which typically required two laboratories in different locations connected by long-distance links that introduced latency and constrained the types of social interaction that could be studied, whereas the Tsinghua facility allows participants to see and hear each other through a direct audio-visual connection without internet intermediation. Each of the two rooms houses a full whole-head TRIUX neo system capable of adult and pediatric recordings, and the open-source software developed by Dr. Andrey Zhdanov ensures unified, real-time experimental control across both systems, with microsecond-level clock synchronization and sufficiently low audio-visual latency to support genuine back-and-forth interaction rather than delayed, asynchronous exchanges.
