The wavelength dependences of the absorption coefficient µ_a (a), scattering coefficient µ_s (b), reduced scattering coefficient ${\mu }_{\text{s}}^{\mathrm{\prime }}$ (c), and scattering anisotropy factor g (d) of the rat healthy brain tissues measured in this paper and presented in Refs. [17–20]. In (b-d) approximations of experimental data using presented formulas are shown.
