Abstract

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_r-L₀) 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)
