Abstract:
1. A measurement system for living bodies, comprising: a measurement unit for measuring the internal state of a subject body; means for detecting the position of a maximum and a minimum of a biological fluctuation component; a signal extraction unit for extracting the biological fluctuation component contained in a signal obtained by the measurement unit, wherein the signal extraction unit outputs a current value of the biological fluctuation component which is the value of the signal measured by the measurement unit at the current time when the signal has been subjected to fitting with a polynomial of degree n in a time window length T, seconds, that is set from the present to the past, n=an integer of 3 or more, 0.01≦(n−1)/2T≦0.5; a stimulus timing determination unit for determining the timing of presentation of a stimulus or instruction to the subject body on the basis of the biological fluctuation component extracted by the signal extraction unit, wherein the stimulus timing determination unit determines the timing of presentation of a stimulus or instruction to the subject body alternately at the maxima and minima of the biological fluctuation component extracted by the signal extraction unit; a stimulus/instruction presentation control unit for controlling the presentation of a stimulus or instruction such that the presentation occurs at the time determined by the stimulus timing determination unit; and a stimulus/instruction presentation unit for presenting a stimulus or instruction to the subject body in accordance with a control signal from the stimulus/instruction presentation control unit.
