Abstract：Objective To discuss the brain function of 134 high performance fighter pilots,and the correlations with concentration index and relaxation index based on the long time (18 minutes) encephalofluctuograph technology (ET) monitoring results.Methods A total of 134 high performance fighter pilots who had aviation medicine training in authors' hospital from January to December in 2016 were selected.Using portable brain analyzer for brain ET detection (18 minutes),the information of neurotransmitter in the brain and brain function were analyzed by electroencephalograph signals.According to different ages,all patients were divided into two groups:under 30 years old group (n =76) and above 30 years old group (n =58),neurotransmitter distribution characteristics between two groups were compared.The correlation between neurotransmitters with the concentration index and the relaxation index were analyzed.Results ①Norepinephrine in the neurotransmitter of brain in above 30 years old group was significantly lower than that in under 30 years old group (P＜0.05).②Brain neurotransmitter γ-aminobutyric acid (GABA) showed a negative correlation with the concentration index and relaxation index,and neurotransmitter dopamine (DA) showed a negative correlation (P＜0.05).Conclusion Brain ET monitoring has effectively reflect the real fighter pilots brain neurotransmitter distribution,state of brain function and the features of the age.The neurotransmitter GABA is the key factor to affect the concentration index neurotransmitters,and DA is the key factor to affect the relaxation index neurotransmitter.It can be an objective basis for evaluating the pilot work status.
