Neuromagnetic responses to repetitive brief sounds were analyzed with Hilbert transformation. It was found that phases and amplitudes of the ongoing oscillation between 3 and 16 Hz were locked and increased, respectively, at around the timings of N100m. The oscillation within each trial was reduced to an equivalent current dipole in the auditory cortex at around the timings of N100m, but not at the other peaks. A model was thereby proposed in which several oscillators were assumed within the auditory cortices, whose phases were locked at around the timings of N100m, but not otherwise. |
