摘要：
The present invention addresses the problem of providing a brain function measurement device and a brain function measurement method with which it is possible to eliminate or minimize the need for a calibration operation. The problem is solved by a brain function measurement device including: a first light irradiation probe S1 which irradiates the brain of a subject with light； a first light detection probe D1 which is disposed adjacent to the first light irradiation probe S1 and detects light reflected from the brain among the light irradiated from the first light irradiation probe S1； a second light irradiation probe S2 which is disposed adjacent to the first light detection probe D1 and irradiates the brain of the subject with light； a second light detection probe D2 which is disposed adjacent to the second light irradiation probe S2 and detects light reflected by the brain among the light irradiated from the second light irradiation probe S2； and a control unit 3 which adjusts the light amount irradiated by the second light irradiation probe S2 so that the light amount measured with respect to a channel between the first light detection probe D1 and the second light irradiation probe S2 becomes an observation value observed with respect to a channel between the first light irradiation probe S1 and the first light detection probe D1, and which adjusts the light amount detected by the second light detection probe D2 so that the light amount measured with respect to a channel between the second light irradiation probe S2 and the second light detection probe D2 becomes the observation value.
