About the use case
What it is and how it works
Hyperscanning is a method for simultaneously recording the brain activity of multiple participants during natural interaction. Unlike a classical experiment with 'one subject in an isolated booth', hyperscanning shows how brains synchronize during dialogue, collaborative problem-solving, learning, and play.
The key technical challenge is a unified timeline. Recordings from multiple headsets are synchronized to common event markers (stimulus onset, dialogue response, game move), after which inter-subject metrics are calculated: correlation of rhythmic activity, alpha and theta phase synchronization, consistency of engagement changes. Wireless headsets also solve the second problem of the method—participants can look at each other, talk, and move, rather than lying in separate MRI scanners.
We build configurations based on group size and task: from a pair of Insight for an educational demonstration to multiple EPOC X or FLEX units with LSL labeling for full-scale research. We assist with synchronization, test recordings, and recommendations for processing inter-subject data—all in Russian.
Metrics
What do we measure in this use case
Key signal indicators on which the methodology is built: from basic EEG rhythms to derived indices.
Intersubject correlation
rhythmic power coherence between participants during interaction moments
Phase synchronization
phase-locking of alpha/theta rhythms between individuals as an index of 'tuning' to each other
Engagement consistency
synchronous bursts of attention and engagement metrics in dialogue
Leadership metrics
who initiates activity changes more frequently — useful in team research
Common event markers
utterances, moves, stimuli — all tied to a single timeline
Channel quality
impedance and artifact control per headset separately
Implementation
How it works
1
Experiment design
We define the interaction task (dialog, negotiations, collaborative game) and the number of participants, and select metrics.
2
Configuration
We select headset sets and a synchronization station, prepare an LSL scenario with common event markers.
3
Pilot recording
We conduct a test session: check impedances, delays, and radio channel quality with multiple devices operating simultaneously.
4
Recording series
We collect data from dyads or groups; video/audio is recorded in parallel for later annotation.
5
Analysis
We export recordings to Python/MATLAB/EEGLAB, calculate inter-subject metrics, and interpret the results.

FAQ
Frequently asked questions about the 'Hyperscanning' use case
How many headsets can be used simultaneously?
In practice, we have worked with configurations of two to ten devices in a single room. The limitation is not the number of headsets, but the radio channel density: with a large number of devices, we distribute the frequency ranges and verify the connection during a pilot recording.
How are recordings synchronized between participants?
Via LSL: all headsets and stimulus sources write to a single timeline with event markers. This is the de-facto standard for psychophysiology experiments and is supported by EEGLAB, MNE, and other packages.
Is hyperscanning suitable for educational courses?
Yes, this is one of the most effective training formats: students see the synchronization of their brain activity in real-time. For laboratory workshops, we typically recommend Insight pairs — quick setup and clear results.
What experiments are typically conducted?
Dialogues and negotiations, collaborative problem-solving, paired learning, team games, research on empathy and trust. The method is applicable wherever the dynamics of interaction between two or more people is important.
Won't the headsets interfere with each other via Bluetooth?
With proper setup—no: devices operate on different radio channels, and during pilot recording we check for packet loss. For dense setups, we use USB receivers and separate workstations.
Do you help with processing intersubject data?
We consult on the pipeline: preprocessing, artifacts, calculation of correlations and phase synchronization, Python and MATLAB packages. Analysis of your data—within technical support.
