Abstract

In this paper, the effects of the cognitive conflicts on cerebral blood flow were considerd. The cognitive conflicts were included by Stroop tests, and the changes in the cerebral blood flow were measured at multiple points, using fNIRS device. It is assumed that the brain activities during the Stroop tests are activated near the left inferior frontal gyrus including Broca's area, which is thought to be devoted to language comprehension. Because of this reason, this region of the brain has been often focused on many researches. However, it seems that the discussions including the other region of the brain, such as the right hemisphere and the frontal parts, using fNIRS, have not been held enough. Correspondingly, the study of the relationship between reaction time and cerebral blood flow seems to be insufficient. In this paper, the changes in cerebral blood flow during Stroop tests were measured using a multi-channel fNIRS device (Hitachi medical Co., Japan). From the results, it is indicated that the changes in the whole-brain cerebral blood flow has increased greater when performing incongruent tasks than performing congruent tasks. At the same time, it is recognized that the reaction time is short, the more the changes in the cerebral blood flow is increased.
