Overview: This paper investigates new approaches to quantifying the white matter connectivity in the brain using Diffusion Tensor Magnetic Resonance Imaging data. Their first approach finds a steady-state concentration/ heat distribution using the three-dimensional tensor field as diffusion/ conductivity tensors. Their second approach casts the problem in a Riemannian framework, deriving from each tensor a local warping of space, and finding geodesic paths in the space. Both approaches use the information from the whole tensor, and can provide numerical measures of connectivity.
