After it keeps hearing a periodic auditory stimulus, it might be able to be recalled like actual sound even if there is no stimulus. In this case it is seemed that a stimulation pattern is memorized and an autonomous signal source with an oscillation pattern like the periodic stimulation is formed in a brain. However, in recalling auditory stimulus experiment, when EEG is ensemble averaged, EP (evoked potential) at the time of the recalling may decrease because subject oneself try to recall auditory stimulus according to same timing as periodic stimulus interval. If SEP (somatosensory evoked potential) can be used as a trigger to recall acoustic stimulus, ensemble average is expected to be applied to attract EP by recalling. But, because SEP occurs by electric stimulation, it is necessary for SEP and AEP (auditory evoked potential) to be the summation characteristics in order to analyze the simultaneous evoked potential of an electric stimulus and auditory stimulus. |
