Аннотация: Rhythmic oscillations of parameters of the oxidative metabolism of the brain were first found in experiments with polarographic recording of the free oxygen partial pressure (pO2) in the brain tissue of animals and man [4, 10-12]. It has been suggested that rhythmic oscillations of pO 2 arise not only because of the rhythmic character of the 0 2 supply to brain tissue (fluctuations of cerebral blood flow and of the pulse and respiration rates), but also because of certain other factors [2]. One such factor may be rhythmic changes in oxidative metabolism of brain tissue, demonstrated experimentally first during recording of the redox potential state (RPS) of the brain [6, 14], and later in fluctuations of the NADPH concentration, measured spectrophotometricaUy [13]. It has been shown in recent years [3] that the periods of a certain part of the spectrum of rhythmic oscillations of cat brain pO 2 are closely connected with the animals' functional state: on the transition from active wakefulness to slow-wave sleep the periods of the oscillations of pO 2 increase. One of us [8] showed previously that rhythmic oscillations of the cerebral cortical RPS of rabbits in the period of defensive-orienting behavior (the state of active wakefulness) are characterized by oscillations with the same period (measuring a few seconds) and of quasisinusoidal form.
