Claim 0:
1. A neurovascular coupling analytical method based on electroencephalogram and functional near-infrared spectroscopy, comprising:
acquiring an electroencephalogram signal and a brain hemodynamic signal;
extracting an event-related potential signal from the electroencephalogram signal;
extracting a first time characteristic from the event-related potential signal;
extracting a hemodynamic response function from the brain hemodynamic signal;
extracting an amplitude characteristic and second time characteristics from the hemodynamic response function wherein the amplitude characteristic of the hemodynamic response function is a peak amplitude, and the second time characteristics of the hemodynamic response function comprises a rising delay, a peak time, and a full width at half maximum;
analyzing a relationship between the first time characteristic of a single component of the event-related potential signal and the peak amplitude of the hemodynamic response function to obtain a first coupling relationship; and
analyzing a relationship between the first time characteristic of the single component of the event-related potential signal and the rising delay, the peak time and the full width at half maximum of the hemodynamic response function, respectively, to obtain a second coupling relationship.
