Neural mechanisms of social interaction between live interacting dyad using hyperscan method

Abstract

Most of the cognitive brain researches regarding human social cognition and interaction investigate how these social abilities represents in a brain. However, in real social environment, communication is dynamic and interactive, and this point seems to be essential. Some of the researchers focus on this live interaction between persons, and employ hyperscanning method which measures more than two brain activities simultaneously. It can be realized with several neuroimaging equipment such as MRI, NIRS, MEG, EEG. Recently, NIRS and EEG hyperscanning studies are increased, because it is relatively easy to set up live interactive situation in experimental room. However, these hyperscan studies using different equipment have several serious issues: difference of measurement parameters and none of integrative analytical method for such hyperscan records. Here, I introduce some hyperscan studies using several equipment, and discuss problem and future of this research field.
