Abstract(in English) | It is well known that both functional magnetic resonance imaging (fMRI) and near-infrared optical imaging (NIRO Imaging) techniques reflect the hemodynamic change associated with alteration in local brain activity. The former reflects a difference in the magnetic susceptibility between blood vessels and surrounding tissue caused by changes in paramagnetic deoxygenated hemoglobin (deoxy-Hb) concentration in the flowing blood, whereas the latter more directly reflects changes in concentrations of both deoxy-Hb and diamagnetic oxygenated hemoglobin (oxy-Hb). In the present study, we aim to clarify the physiological interpretations of data obtained with fMRI and NIRO Imaging during sensory stimulation in humans. Further, we show a successful description of the fMRI signal as a function of concentrations of deoxy-Hb and oxy-Hb obtained with NIRO Imaging. |
