摘要：Disclosed is a biopotential analysis system and method of the present invention for determining, in a noninvasive manner, cerebral electrical properties. A suitable electrode and amplifier system is used to obtain biopotentials from the region of interest. Surface electroencephalographic signals are then digitized and transmitted over a serial RS232C line to a host computer where a two minute long signal is divided into 30 consecutive four second intervals. A fast Fourier transform (FFT) is then performed on every interval, and the resulting fast Fourier transforms are then used to produce bispectral complex triple product and bispectral real triple product arrays for that interval. The complex triple product arrays of all intervals are added together, and the real triple product arrays of all intervals are also added together. Each element in the final complex array and final real array is then divided by 30 (the number of intervals) to produce an average complex triple product array and an average real triple product array. The magnitude squared of each element in the complex triple product array is divided by the corresponding element in the real triple product array to form the bicoherence array. The bicoherence array is displayed on a video terminal or plotted, and is used as a figure of merit for the assessment of cerebral electrical function.
