    Neuroimage 25:701-7. 2005
    ..The ratio of fractional changes in oxidative metabolism to fractional change in blood flow was found to be 0.56 +/- 0.08, in general agreement with previous studies of flow-metabolism coupling...

    Harvard Medical School Graduate Program in Biophysics, Massachusetts General Hospital, Charlestown, MA 02129, USA
    Neuroimage 29:368-82. 2006
    ..The observed co-variance in these parameters between subjects is in agreement with hemodynamic models and provides further support that fMRI and NIRS have similar vascular sensitivity...

    Unité de Neuroimagerie Fonctionnelle, Centre de Recherche, Institut Universitaire de Geriatrie de Montreal, Department of Physiology, Universite de Montreal, Montreal, Canada
    Neuroimage 50:1074-84. 2010
    ..Finely, we believe that the use of controlled global stimuli, such as hypercapnia, will help assess the effectiveness of new acquisition techniques...

    Phys Med Biol 48:2405-18. 2003
    ..A more precise estimate of the flow-consumption ratio will require better estimates of the model parameters or flow information, as can be provided by combining NIRS with fMRI...
