EEG analysis device, EEG analysis system and EEG analysis program

摘要

An EEG analysis deviceFrom the spectrum obtained by frequency analysis of time series data of EEG measured at a predetermined site of the head of the subjectThe first frequency band for the characteristic of the intensity of the wave intensity within the second frequency band occurring in the first frequency band of the higher frequency band than the ratio of the features of the intensity of other waves in the first frequency band of the higher frequency band to the characteristic of the strength of the wave within the first frequency band generated under stress The first ratio, which is the ratio of the characteristic of the wave intensity within the interiorA calculation unit (301) which calculates a second ratio which is the ratio of the characteristic of the intensity of the wave intensity within a third frequency band generated in the sleep state to the characteristic of the intensity of the wave in the second frequency band occurring in the wakefulness state andFirst ratioFirst reference value determined from the first ratioThe second ratioBased on the second reference value determined from the second ratioAn estimation part (302) for estimating the state of the subject and.
