A New Recognition Method for the Auditory Evoked Magnetic Fields

Comparison of the average AEFs in the MEG and the average AEPs in the EEG. (a) The average AEFs in the MEG. By comparison with the AEPs in the EEG, AEFs in the MEG also contain three peaks which are P50 at 68 ms, N100 at 108 ms, and P200 at 193 ms after stimulation, respectively. Time 0 in the picture is the time when the stimulus occurs. (b) The average AEPs in the EEG. There are three distinct peaks occurring at the same time in the MEG. These peaks have been extensively verified and observed in EEG experiments. (c) Spatial distribution of the EEG electrodes.
