Abstract
A neurovascular coupling analytical method based on an electroencephalogram and functional near-infrared spectroscopy includes: S: acquiring an electroencephalogram signal and a brain hemodynamic signal; S: extracting an event-related potential signal from the electroencephalogram signal; S: extracting a time characteristic from the event-related potential signal; S: extracting a hemodynamic response function from the brain hemodynamic signal; S: extracting an amplitude characteristic and time characteristics from the hemodynamic response function; and S: analyzing influence of the time characteristic of the event-related potential signal on the amplitude characteristic and the time characteristics of the hemodynamic response function to obtain a coupling result. The time characteristic of the event-related potential signal is a delay. The amplitude characteristic of the hemodynamic response function is a peak amplitude, and the time characteristics of the hemodynamic response function comprises a rising delay, a peak time, and a full width at half maximum.
