EEG steady state synchrony patterns sonification

This paper describes an application of a multichannel EEG sonification approach. We present results obtained with a multichannel-sonification method tested with steady-state EEG responses. We elucidate brain synchrony patterns in an auditory domain with utilization of the EEG coherence measure. The transitions in the synchrony patterns are represented as timbre (i.e., spectro-temporal) deviation and as spatial movement of the sound cluster. Our final sonification evaluation experiment with six subjects confirms the validity of the proposed brain synchrony-elucidation approach.
