In this report, we compare the hemodynamic change at frontal lobe by ingestion of glucose. The brain activity is evaluated by the form of oxidized hemoglobin concentration, measured by wearable optical topography system. The data are measured during Paced Auditory Serial Addition Test (PASAT) which is known for its usefulness in the area of attentional dysfunction in cognitive rehabilitation. Properties of blood flow change are estimated by transition of time-series data or principal components analysis as well as the relation between blood sugar level and activation in frontal lobe.
