Enhancing social interaction through real-time two-brain imaging

The brain mechanisms underlying social cognition and interaction are poorly
understood. Recent studies have shown that people’s brain rhythms synchronize when
they engage in social interaction with each other. However, the functional
significance of inter-brain synchronization (IBS) is unknown. It has been proposed
that IBS has a crucial function in facilitating mutual understanding and cooperation. If
this is indeed the case, then inducing IBS should enhance subsequent interaction. This
will be investigated by employing a two-brain real-time EEG imaging framework,
whereby people synchronize their neural oscillations with each other through
neurofeedback, and testing the causal effect of achieved IBS on subsequent social
coordination. If successful, this would give insight into the brain basis of social
interaction, and have huge implications for non-invasive social enhancement
technologies, which can be used to enhance well-being and social cognition in people
with social deficits.
