Abstract
⺠Pial vasculature contaminates the NIRS signal. ⺠Concurrent NIRS-fMRI recordings enables estimation of the cortical signal contribution. ⺠20% of the HbR signal and 75% of the HbO signal has cortical origins (finger tapping). ⺠HbT should be used rather than HbO or HbR to map cerebral activity with NIRS.
