| Research Abstract |
During MEG studies to detect neural activities associated with various cognitive states, we observed specific responses elicited by synthesized complex sounds, sequences of musical chords and tone-sequences differing in pitch between the two ears that induce auditory illusion. We also measured modulation of alpha-wave in response to a visual object that mimicked collision and pictures of living objects, from which estimation of subjects' expectation or affection was made.
