Abstract

Klimesch (1995a, 1995b) and Verleger (1995) agree that the main power of the event-related potential (ERP) P300 is in the delta range. Klimesch, however, adds that the theta range is also of importance for the P300 response. This commentary summarizes results of ERP analysis in the frequency domain confirming the major importance of the delta response for the P300 wave. A role of the theta response for the P300 wave, however, is also demonstrable. Furthermore, our experimental data show that other frequency ranges also contribute to the P300 response. To our mind, this controversy is just an example of the recent trend towards a functional interpretation of event-related (or induced) brain rhythms.
