Abstract

In his commentary, Verleger (1995) argues against the proposal that the P300 is due to phase locked theta activity (1995). He points out that most of the power of the P300 lies in the delta range. Furthermore, he emphasizes his opinion that without incorporating a variety of ERP-experiments, any theory about brain physiology and memory will be incomplete. In my reply I refer to data which indicate that regardless of the effects of other frequency bands, theta power significantly influences the amplitude and latency of the P300. With respect to incorporating results from ERP-experiments, I argue that what would be needed is a direct comparison between ERP-results and results from comprehensive spectral analyses. For reasons outlined below, a critical issue for such a comparison would be to determine frequency bands individually for each subject.
