261名歼击机飞行员脑波α频段涨落图特征的研究

为探讨飞行员脑波α频段涨落图特征，应用脑功能脑电－涨落图（ＥＥＧ－ＥＴ）评价技术，研究了２６１名歼击机飞行员脑波α频段的涨落图特征。结果显示：飞行员的脑波α频段频率涨落竞争结构的主涨落成分为９Ｈｚ，次涨落成分为１０Ｈｚ，７Ｈｚ在涨落优势序排列占第三位。频率涨落竞争结构相对熵值平均为（７２±１４）％，枕区的导联Ｏ１、Ｏ２的相对熵值低，分别为（６９±１７）％和（６７±１８）％。脑波α频段功率涨落功率谱

A study on EEG-Encephalofluctuographic characteristics in alpha frequency band in pilots]

The frequency-fluctuation characteristics in alpha frequency band were studied by EEG-Encephalofluctuographic Technology (EEG-ET) in 261 pilots. The electrical activity was recorded from 12 scalp monopolar leads of the international 10-20 system using linked ear lobes as reference. The components of the competitive frequency-fluctuation structure in alpha frequency band was analysed. The results showed that the predominant frequency component of the competitive structure was 9 Hz in the 261 normal healthy pilots. The second was 10 Hz. And the third was 7 Hz. The other competitive frequency components were inhibited. The relative entropy value (percentage) of the competivity structure was calculated for each EEG derivation of each pilot. We also analysed the spectra of the EEG-Encephalofluctuograph. We found that there was a dominant power peak at 21.39mHz in 57 pilots who complained in-flight blackout sometimes during acceleration.
