| Outline of Final Research Achievements |
We performed connectivity-based parcellation of brain regions such as the amygdala, which is a complex structure composed of a heterogeneous group of nuclei and subnuclei, using diffusion-weighted imaging and probabilistic tractography. The subregions of the amygdala were segmented based on the connectivity pattern between the amygdala and other brain regions. As a basis for connectivity-based parcellation, we evaluated the effects of scanning conditions and image correction methods on morphometric and diffusion-weighted imaging.
