Global Connectivity estimation: Results

In this section, we present some results of applying this methodology to the estimation of connectivity distributions from voxels in human thalamus. Knowledge of thalamo-cortical connectivity is sparse in human, but rich in primate. These results, and others, are analyzed, interpreted and compared with the non-human literature in detail in [8]. Here we present them as a first step toward validation of probabilistic tractography as presented in this paper, and evidence suggesting that connectivity studies are feasible with diffusion weighted imaging, even between Gray matter structures.
