Figure 2. Analysis of structural connectivity.

Figure 2.

Top panel: Diffusion tensor imaging (DTI), measures are all based on different ratios of diffusion restriction, leading to relatively isotropic or anisotropic tensors. Both CSF and grey matter show isotropic diffusion, while white matter shows anisotropic diffusion. In DTI each voxel is modeled with a single tensor. Lower panel; Neurite orientation dispersion and density imaging (NODDI) models tissue as three separate compartments, allowing determination of separate contributions of free water (CSF), neurite density (axons and dendrites), and orientation dispersion (myelination).
