[UBioelectric activity of the brain of cats in wakefulness and various sleep stages in cats].

Multiple recording of biopotentials with implanted electrodes from the globus pallidus, caudate nucleus, putamen, ventro-lateral thalamus, thalamic center median, midbrain reticular formation, and the posterior hypothalamus, was carried out. Peculiar features were noted during slow-wave sleep in the activating RF. However, disappearance of these features during transition to fast sleep and persisting slow potentials in some structures at that suggest the hypnogenic system to be rather complicated in its spatial-temporal structure and not to be associated with just a single "leading" structure as, for example, the RF.
