During the analysis of experimental records of intracranial EEGs of rats in sleep, wakefulness and after sound exposure, we have shown that statistical measures characterizing the features of individual and collective dynamics of the electrical activity of the brain in the δ-frequency range make it possible to classify the state of the animal. The factor determining such changes in EEGs is a change in the rate of cerebral fluid drainage, which is confirmed, in particular, by the similarity of the properties of low-frequency electrical activity of the brain during sleep and after auditory exposure, in contrast to the state of wakefulness.
