The solution of the problem of finding the depth of anesthesia or the level of unconsciousness by monitoring the electroencephalogram (EEG) is considered. The bispectrum analysis of the EEG of a dog is studied to determine any trends with increasing depth of anesthesia. Of the four channels of EEG analyzed, channel 1 (L/sub r/-L/sub 0/) seems to show a strong coupling between frequencies in the range of 6-10 Hz around 78% of the time when the dog is asleep (depth = 1.0) and a weak or no coupling between frequencies in the same range around 67% of the time when the dog is awake (depth = 0.0).
