[Retention of the skill to perform adaptive bio-control of bioelectrical activity synchronization in the human brain cortex in an argon-nitrogen-oxygen atmosphere with various oxygen content].

The best method to prevent fire incident in space vehicles and other habitable pressurized modules is reduction of atmospheric oxygen concentration (hypoxia). Atmosphere doping with argon may ease tolerance of this hypoxia by humans. Mental performance in Ag-N2-O2 atmosphere with various oxygen content was assed by: retention of the skill to perform adaptive biocontrol (ABC) of bioelectrical activity synchronization in the frontoparietal and parietooccipital cortex (EEG); emotional and mental state (Luscher test); work successfulness (completion of PC games "Miner"and "Tetris"). The Ag-N2-O2 atmosphere did not affect, despite the fluctuation of anxiety, simulated work completion and long-term (within 24 hours) retention of the relevant to ABC skills.
