In this study we developed a new method to analyze the thalamus and its constituent substructures based on probabilistic tractography. Probabilistic tractography is an MRI technique that estimates the likelihood of connection between two points in the brain by sampling the distribution of greatest diffusion directions in each voxel of the brain image. In contrast to the previously published methods, which are applied at the group level, our method can be used to analyze the thalamic substructures in individual datasets.
