内容記述 | In this paper, the relationship between a working memory capacity and a brain activity were evaluated using the results of a Reading Span Test (RST), which is a language working memory task. A cerebral blood flow change is one of the indexes of evaluating brain activities. functional Near-infrared Spectroscopy (fNIRS) is a non-invaded device to detect a cerebral blood flow change, so that it can be used to figure out the activated area of brain activities. In this paper, we focus on dorsolateral prefrontal cortex (DLPFC) and the left inferior frontal gyrus (LIFG) as regions of interests (ROI). Functional activation of these ROIs was examined using fNIRS. It has been reported that DLPFC is responsible for continuing cautions, while LIFG manages language processing. Through the experiments, the following three points were observed. First, the functional relation between DLPFC and RST was observed. The subjects were classified into two groups; a high score and a low score groups. The cerebral blood flow changes in of the subjects in the low score group were greater than that of the subjects in the high score group. Second, in the both groups, LIFG was activated with the different active patterns; In LIFG, the brain activity was constant for in the high score group, while it was declining in the low score group. Lastly, the brain activity in the DLPFC region for the low score group increased. | |||||||||||
