Outline of Final Research Achievements

The m-sequence modulation method has been developed as a technique to extract event-related potentials and associated signals from electroencephalograms and magnetoencephalograms without averaging in a short period of time. In this project, we focused on autism spectrum disorders (ASD). More specifically, we tried development of a practical method of measuring human voice-specific response using m-sequence modulation method, with socially atypical children with ASD in mind. It was found that when healthy adults listen to m-sequence modulated human voice, voice-specific responses can be obtained from a few electrodes in the right hemisphere in their beta power.
