Neuromagnetic signals above the auditory cortex were passed through a band-pass filter between 3 and 16 Hz and then divided into analytic (instantaneous) amplitudes and phases by Hilbert transformation. Both the amplitudes and phase-locking were increased, on average across the trials, at around the timing of N100. These facts per se failed to prove the “phase-locking model”, however, as a possible mechanism for generating the auditory evoked fields, because simulation of the alternative “signal plus noise model” also yielded the same averaged results. Instead, analysis in each of the trials revealed sudden phase resets at random timings associated with “waning” of the amplitudes, which supports the “phase locking model” with a stochastic sense. |
