Abstract

In MEG studies, cortical activities around the human auditory cortex were found to be evoked by randomly occurring infrequent stimulus changes, e.g., in tone frequency or in tone intensity, among a monotonous sequence of tones [1]. Some studies using random stimulus omissions also found evoked ‘endogenous’ responses by the ‘missing’ stimulus itself [2, 3]. However, the location of the activities differed between the two types of studies. In this study, we employed the same ‘missing’ tone sequence in MEG and fMRI measurements and investigated the activities around the superior temporal auditory cortex.
