OBJECTIVE
To study EEG during simulated flight training, then to explore the situational character of mental fatigue of the pilots.
METHODS
Fifty male pilots were randomly choice to be recorded their EEG including rest,flight and recovery phase. Then the band waves of EEG were analysed among the three phase.
RESULTS
(1) During flight, the amplitude of alpha, beta, SMR, theta, gamma waves tended to increase. These changes seemed obviously in SMR, theta waves. (2) After flight, all the amplitude of the waves declined except for beta wave of the right lobe,and most of them were still higher than those before flight (P < 0.05); (3) The right brain showed a higher cerebration than the left, especially in theta wave.
CONCLUSION
Mental fatigue is started during the flight training, and the right lobe has a severe mental fatigue than the left. After flight, mental fatigue showed a slow recovery.
目的
研究模拟飞行训练期间的脑电图（EEG），进而探究飞行员心理疲劳的情境特征。
方法
随机选取50名男性飞行员，记录其在休息、飞行和恢复阶段的脑电图。然后分析三个阶段脑电图的波段。
结果
（1）飞行期间，α波、β波、感觉运动节律（SMR）、θ波、γ波的振幅趋于增加。这些变化在SMR、θ波中似乎更为明显。（2）飞行后，除右叶β波外，所有波段的振幅均下降，且大多数仍高于飞行前（P<0.05）；（3）右脑的活跃度高于左脑，尤其是在θ波方面。
结论
心理疲劳在飞行训练期间开始，且右叶比左叶存在更严重的心理疲劳。飞行后，心理疲劳恢复缓慢。
