摘要
A driving fatigue related EEG function connection dynamic characteristic analysis method, comprising: preprocessing EEG data by using independent component analysis and wavelet packet transform (S1); constructing the preprocessed EEG data into a dynamic characteristic time brain network on the basis of a sliding window method (S2); measuring a spatio-temporal topology of the time brain network on the basis of a time efficiency analysis framework (S3); and performing statistical analysis on the spatio-temporal topology of the time brain network, and obtaining a correlation between a driving fatigue related behavioral expression and the dynamic characteristics of the time brain network (S4). The time brain network with the dynamic characteristics is constructed by introducing the time characteristics into a driving fatigue static network, a spatio-temporal recombination rule of the time brain network during driving fatigue can be obtained by means of statistical analysis, and a more accurate analysis result is achieved, thereby facilitating displaying more key dynamic characteristics of information transfer function recombination between brain regions related to driving fatigue in a fine time scale.
