When complex tones consisting of four or more continuous harmonic tones of a certain fundamental frequency are perceived as the pitch of the fundamental frequency, it is referred to as the missing fundamental phenomenon (MFP) or the virtual pitch. We reported that MFP occurred in the human transverse and superior temporal gyri, namely, the primary auditory cortex, between P50 and N100 by 306 ch magnetoencephalography (MEG). It is also reported that auditory selective attention probably occurs in the human auditory cortex. The purpose of this study was to investigate whether MFP was produced in the same process even during auditory selective attention. We measured MFP by 306 ch MEG. The subjects had two tasks. One task was listening to some complex tones while counting the total numbers of the target tone (attention task), and the other task was accomplished while ignoring the target tone (no attention task). MFP also occurred in the transverse and superior temporal gyri between P50 and N100 even in the case of auditory selective attention, the same as in that of the without attention atmosphere. MFP and auditory selective attention occurred in the human auditory cortex at adjoining locations. |
