Abstract :
Bispectral analysis is used in this paper to examine the status of quadratic phase couplings in developing neuronal interactions of two hippocampal subfields, CA1 and the dentate gyrus. It was found that the frequency bands where active quadratic phase coupling occurs gradually shift from a low theta range (5-7 Hz) for animals of 15 days of age to a high theta range (6.5-8.5 Hz) as animals mature at an age of 90 days. Results of this study indicate that bispectra can be effectively used to quantify the maturation changes of the EEG obtained from CA1 and the dentate gyrus
