Functional cerebral hemodynamic signals obtained by near infrared spectroscopy (NIRS) and functional magnetic resonance imaging (fMRI) were compared. The contribution of superficial layers such as the skin and skull to the NIRS signal was examined. The study was conducted on six healthy right-handed male volunteers. A direct temporal correlation between the NIRS and intercranial signals was demonstrated in 50% of the subjects.
