Abstract
In a brain-wave analysis apparatus, an electrical brain-wave signal is analyzed for purposes of diagnosis by detecting the time interval between adjacent ones of the intersections of the brain-wave signal with a predetermined level, and the peak value and the wave-form area of the brain-wave signal in the said time interval, or the amplitude value of the brain-wave signal every constant period of time. The said time intervals, peak values, wave form areas, and amplitude values are each classified according to their magnitude, accumulated and stored; and said information is used to prepare histograms. The histograms are analyzed by a processor to obtain their standard deviations, and variations in the standard deviations with time are displayed or recorded to provide a basis for diagnosing living body conditions.
