Project Title: Comparative anatomy of anterior temporal white matter tracts in macaques and humans

Dr. Bullock's doctoral work focused on the detailed comparison of accounts of major white matter tracts and the development of open-source tools for generating models of these structures. With these endeavors he has worked as an active member of the growing community of researchers actively seeking to forge consensus in the burgeoning field of digital white matter anatomy. As a member of the CMRR team he will be working with Professor Sarah Heilbronner and Professor Jan Zimmermann to leverage tract-tracing and high resolution dMRI to better understand the complex architecture of the brain's white-matter. The resulting tools and insights will be used to develop biological priors for the next generation of tractographic and connective models of the brain, thereby permitting more precise accounts of how the brain's wiring shapes and is itself shaped by behavior, dysfunction, and changes throughout the lifespan.
