为研究射击瞄准过程中脑网络与射击性能的关系，采集了40名熟练射击运动员在步枪射击过程中的脑电图信号，计算了脑电图功能耦合、脑功能网络拓扑结构以及脑电图特征与射击性能的相关系数。我们的研究结果表明，射击表现与右脑前额叶、额叶和颞叶区域在Beta1和Beta2频段的功能耦合呈显著负相关。整体和局部脑网络拓扑特征也与射击表现显著相关。研究结果表明，在这些实验条件下，射击性能越高的射击者在射击过程中表现出较低的功能耦合、较高的全局信息集成效率和较低的局部信息集成效率。这些结论可为研究射击者射击时的心理状态提供脑电网络的理论依据。
To study the relationship between brain network and shooting performance during shooting aiming, we collected electroencephalogram (EEG) signals from 40 skilled shooters during rifle shooting and calculated the EEG functional coupling, functional brain network topology, and correlation coefficients between these EEG characteristics and shooting performance. Our result shows a significant negative correlation between shooting performance and functional coupling between the prefrontal, frontal, and temporal regions of the right brain in the Beta1 and Beta2 frequency bands. Global and local brain network topology characteristics were also significantly correlated with shooting performance. These findings indicate that under these experimental conditions, shooters with higher shooting performances exhibit lower functional coupling, higher global, and lower local information integration efficiency during shooting. These conclusions may provide a theoretical basis of the EEG brain network for studying the mental status of shooters while shooting.
