Article Synopsis
- - Prior research indicates potential gender differences in how men and women respond to hypoxia, prompting a study involving 60 student Naval Aviators (30 women, 30 men) to investigate these differences in brain activity and performance under simulated altitude conditions.
- - The study found that women experienced greater decreases in theta (19.4%) and gamma (42.2%) frequency power compared to men (9.3% and 21.7%, respectively) under hypoxic conditions, suggesting a stronger impact on women's neuronal activity.
- - Results highlight that while both genders show brain wave suppression due to hypoxia, the significant differences discovered could inform the design of next-gen aviation helmets, potentially integrating this technology for early warning systems in aviation
Dry-EEG Manifestations of Acute and Insidious Hypoxia During Simulated Flight.

February 2019
Recently, portable dry electroencephalographs (dry-EEGs) have indexed cognitive workload, fatigue, and drowsiness in operational environments. Using this technology this project assessed whether significant changes in brainwave frequency power occurred in response to hypoxic exposures as experienced in military aviation. There were 60 (30 women, 30 men) student Naval Aviators or Flight Officers who were exposed to an intense (acute) high-altitude (25,000 ft) normobaric hypoxic exposure, and 20 min later, more gradual (insidious) normobaric hypoxic exposure up to 20,000 ft while flying a fixed-wing flight simulation and monitored with a dry-EEG system.
