Abstract

The hippocampal averaged evoked potentials (AEPs) of the cat brain were analysed using a theoretical filtering method. Application of ideal low pass filters with different cutoff frequencies supports and enlarges previous findings and interpretations of Başar and Özesmi (1972) based on frequency characteristics of the hippocampus: This brain structure has significant beta frequency (18–35 Hz) selectivity near its typical theta (3–8 Hz) resonance. Moreover oscillatory hippocampal waveforms are predicted. The use of pass band and stop band filters allows one to derive conclusions and principles for the analysis and understanding of averaged evoked potentials in general.
