Abstract(in English) We used near-infrared spectroscopy (NIRS) to measure the changes in hemoglobin concentration in the lateral occipital regions during the shape matching and position matching tasks. In the shape matching task, the participants were asked to judge whether successively presented stimuli were identical in shape to the remembered target. In the position matching task, the participants judged whether successively presented stimuli were identical in position to the remembered target. Concentration of oxygenated hemoglobin in the lateral occipital regions was higher for the shape matching task than for the position matching task. This suggests that pronounced activity was present in the lateral occipital regions during shape recognition. The present study, consistent with the former fMRI and PET studies, supports the usefulness of NIRS for monitoring cognitive brain functions.
