Abstract :
We discussed the influence of optical properties on light propagation in terms of the results of time-resolved NIR brain function experiment using adult heads. The results show that CSF (cerebrospinal fluid) does have some scattering and absorption; the change in the absorption coefficient influences not only the falling part of temporal profile but also the rising part.
