[Disruptions of instrumental alimentary conditioned reflexes after removal of the frontal and parietal associative cortex in the cat].

The influence of the extirpation of the frontal and parietal association cortical areas on the elaborated stereotype of instrumental alimentary conditioned reflexes was studied in cats. Errors in reinforcement choice, disturbance of inhibitory conditioned reflexes and appearance of intersignal reactions were observed. The disturbances were more pronounced after the extirpation of the parietal cortex.

[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.
