[Rhythms of slow-wave sleep and wakefulness in fluctuations of the potential of the oxidative-reductive status of the cerebral cortex].
A method of recording slow ROSP's changes of the brain in chronic animals was used. It has been shown that wakefulness was accompanied by quasisinusoidal oscillations of ROSP (periods--several seconds). During slow sleep, oscillations of ROSP became more complicated and their periods were longer. It is suggested that transitions from sleep to wakefulness and vice versa are connected with removal of maximums of oxidative metabolism tension between biochemical systems characterized by different rhythms of self-regulation. Rhythmic oscillations of ROSP reveal the possibility of separate functional system of the ROSP of the brain cortex to synchronize their oscillations in the brain tissue (biochemical synergism).
