[Effect of graded hypoxia and sodium oxybutyrate on the EEG of monkeys]

The effect on the EEG of a gaseous hypoxic mixture with 10 per cent of oxygen per se and with superimposed action of sodium oxybutyrate in a dose of 50 mg/kg was investigated in tests on macacas rhesus. Following introduction of sodium oxybutyrate an elimination of deviations from the initial EEG findings was registered.
