左右转向驾驶行为脑功能网络关联性分析

Correlation analysis of EEG functional connectivity during driving behavior:turning left and right

为了探讨驾驶左右转向行为过程中脑功能网络关联性与脑电位变化规律,采用无线惯性运动捕捉系统和脑电信号采集设备,同时获得驾驶员脑电信号和左右转向驾驶行为过程中驾驶员手臂姿态数据,利用Pearson相关性方法分析驾驶员脑电信号特征与驾驶员左右转向行为的关系。建立实际驾驶过程中左右转向行为的脑功能网络关联图谱,分析左右转向过程中脑功能区电位的变化规律,实验结果表明驾驶过程中左右转向行为所引起的脑电位变化情况与想象运动过程中脑电位变化情况相同。

To explore intrahemispheric cortico-cortical EEG functional connectivity and the change rule of neuroelectricity during the left and right turning behavior,wireless inertial motion capture system and EEG signal collecting device were used to simultaneously obtain the data of EEG signals and arm joint acceleration from driving behavior,Pearson correlation method is applied to analyze the relationship between the characteristics of driver’s EEG and left and right turning behavior.The brain functional network correlative graph is established during real driving process,the electric potential change rule of brain functional region during left and right turning behavior is analyzed,the experimental results indicate that the neuroelectricity changes of left and right turning during driving process are the same with the changes during imagined movements.
