[Locating the impairment of human cognitive function during hypoxia].

Objective. To find the location where the human brain cognitive function impairs under hypoxia. Method. 14 healthy males, aged 18-20 years, performed auditory Oddball test of two different intensities (55 dB, 80 dB) during exposure to 5000 m by breathing low oxygen mixture. EEG and Reaction Time (RT) were recorded. P3, the component of ERP, was extracted from EEG. P3 latency and RT were used as indices of the experiment. Additive Factors Method was used to analyse the result of the experiment. Result. Interaction between hypoxia and stimulus intensity was found for P3 latency and RT. Conclusion. Acute hypoxia influences the preprocessing stage of information processing.
