| 1. An optical organism measurement system comprising:
a light source that irradiates light to a living body;
a detector that detects light having been irradiated from the light source and having propagated through the living body;
an arithmetic unit that calculates measured data, which represents a change in the concentration of oxidized hemoglobin in
the living body and a change in the concentration of deoxidized hemoglobin therein, on the basis of light detected by the
detector; and
a memory unit in which the data measured from the subject during a first period and the data measured therefrom during a second
period different from the first period are stored,
wherein:
the arithmetic unit classifies the measured data according to each of an increase or a decrease in the concentration of oxidized
hemoglobin and an increase or a decrease in the concentration of deoxidized hemoglobin; and
the optical organism measurement system further comprises a display unit that displays the classification of the data measured
during the first period and the classification of the data measured during the second period.
