[Possibilities and initial results of the determination of reaction time in routine EEG recordings].

The simple reaction timing method permits simultaneous observation of bioelectric factors affecting the times during synchronous EEG recording. The attention functions were checked during paroxysmal peak potential activity by measuring the reaction time. In only a few patients was there no change in the reaction time observed during paroxysmal peak activity. The first results, which are presented here, give rise to many questions in respect of diagnosis, therapy and medical opinion.
