title: Near-infrared study of the underlying physiology of the functional magnetic resonance signal in humans during hypoxia.
abstract: We use near-infrared spectroscopy to investigate hemodynamic changes in humans during a breath holding exercise and their influence on the BOLD fMRI signal. We have quantitatively compared the BOLD fMRI signals with the hemoglobin concentration changes using correlation analysis of NIRS and fMRI data.
