Cortical EEG power spectra associated with sleep-awake behavior in the rat.
Power spectral analyses were used to study cortical EEG activities during sleep-awake behavior in the rat. EEG spectra, both long-time and sequential short-time, derived from EEG during the states of wakefulness, sleep, and REM sleep were qualitatively and quantitatively different. The degree of inter- and intrasubject variability between these spectra was minimal. This experimental model with the rat should allow quantitative delineation of cortical EEG changes produced by psychotropic drugs.
