Nonlinear analysis of the sleep EEG at hippocampal subfields
Taikang Ning, Joseph D. Bronzino · Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society · 1992
Nonlinear signal processing method was used to examine the EEG collected at hippocampal subfields CAl and the dentate gyrus during REM sleep. Bispectral analysis revealed that intra- and inter-quadratic nonlinear interactions exist between CAl and the dentate gyrus in the frequency band of 6–8 Hertz.
