The detailed modeling behind neurite orientation dispersion and density imaging (NODDI). The observed signal at a voxel (A_total) is explained by the contribution from the constituting compartments, as well as how each compartment is modeled. See the text for full description. d_||, parallel diffusivity; d_⊥, perpendicular diffusivity; d_in, rate of diffusion along individual neurites; f_fw, free water fraction; f_in, neurite density index.
