| Research Abstract |
The bicoherence spectrum of electroencephalogram under anesthesia was examined using wavelet analysis. When the concentration of sevoflurane was changed from 1% to 3%, the wavelet bicoherence analysis was continuously performed by EEG signal of 2-seconds, and compared with the bicoherence plot using conventional bicoherence analysis. As the result, the bicoherence peaks in alpha and delta theta bands were detected, and these peaks were matched to the bicoherence peaks by traditional bicoherence analysis. The usefulness of wavelet bicoherence analysis in transitional periods was suggested.
