Abstract :
Bispectral analyses were utilized to study the rat electroencephalogram (EEG) to extract information regarding phase coupling. The results indicate that the EEG recorded from the hippocampus exhibits a strong phase coupling between frequencies in the theta band (6-8 Hz) primarily during REM sleep, while the cortical EEG exhibits a weak coupling between flow frequencies in the delta band (0-3 Hz) during quiet-waking. The degree of phase coupling was further quantified using the biocoherence function. This study provides data not available from traditional power-spectral analysis
