We believe our new hyperscanning-EEG method is well suited for identifying asymmetric neural mechanisms during real-time social interaction. The methodology has an added benefit of being expandable to multi-brain microstates for investigating group interactions.

While we acknowledge that two-brain microstates were unable to pick up on interaction-related differences, possibly due to the low-level task, or IBS - probably because microstates focus on global neuronal brain states, overlooking smaller spatially focal synchronised processes....

Source localisation indicated that the difference in microstate dynamics between symmetric and asymmetric conditions was likely modulated by a difference in default mode network related activity between the two participants when they took on different interactive roles.

Pseudo-pairs also showed a significant difference in two-brain microstate dynamics for the asymmetric tasks, and there was no difference in dynamics between the real pairs and the pseudo-pairs, suggesting that the changes were not specific to the interaction, but rather the asymmetric tasks.

In order to discern whether the changes in two-brain microstate dynamics were specific to the interaction itself, as opposed to the asymmetric behavioural task, we computed the microstate features for pseudo-pairs (i.e. pairs that did not interact with each other).

Interestingly, some of the two-brain microstates were similar to the conventionally determined single-brain resting state microstates, e.g. with dA1, dB1, dC1 and dD1 resembling our single-brain microstates A, B, C and E; and dE2, dF2, dG2, and dH2 also resembling A, B, C, and E, respectively.

Our key finding: We show that traditional single-brain microstates don’t distinguish interaction conditions—but two-brain microstates do! Asymmetry in brain states emerges in asymmetric social roles (i.e., observer-actor, leader-follower).

The participants produced movements across a number of interactive (when they could see each other) and non-interactive conditions. They also engaged in two conditions where they had asymmetric tasks (actor/observer) and roles (leader/follower). Data from: royalsocietypublishing.org/doi/full/10....

Using EEG hyperscanning in a mirror-game paradigm, where two people improvise and synchronise motion together, originally developed by Lior Noy et al. www.pnas.org/doi/full/10....

A two-brain microstate could thus consist of a stable configuration of a specific activity in 1 participant and a different pattern in the other participant, if that particular combination of asymmetric brain states often occurred simultaneously.

Two-brain microstates quantifies quasi-stable moments of synchronous as well as asymmetric activity across different interaction conditions - here applied to an experiment employing the mirror game. We compare our method to the classical single-brain microstate analysis.

The method can identify spatiotemporal interpersonal asymmetries in neural activity patterns, which may emerge in real-time social interactions but are still related to functionally relevant neural processing in individual brains.

We developed this new hyperscanning method in order to better understand functional neural mechanisms that underlie different types of social processes and interactive outcomes, while still taking advantage of simultaneous neural recordings in interacting individuals.

Neural mechanisms underlying social interaction are still poorly understood. Most hyperscanning studies focus on inter-brain synchrony (IBS), but this doesn’t capture asymmetric neural processes in real-time interactions. We propose an alternative approach.
