Auditory event-related potentials (ERPs) were assessed in 6 normal subjects in awake state when the oddball paradigm were manipulated repeatedly 3 or 4 times to study the reemergence of P300-amplitudes and the characteristics of a single P300 wave form by the adaptive correlation filter. As the results, the grand average of P300 correlation values had a tendency to decrease from the third session but was not stastically significant. In only two subjects, it was significant at the final session.
The single P300 wave form which had a rapid descendent slope was asymmetrical. The duration was about 200ms. The averaged peak latency jitters was 22ms, SD, 22.
