Despite its importance, little is known on the evolution of the mammalian brain. Previous work suggests that body size and behavioral function are intertwined in their influence on the evolution of the brain. Most previous studies focused on examining gray matter. Because the underlying white matter connectome facilitates the connections between gray matter areas, it must have simultaneously evolved to support gray matter evolution. In this work we used a wide comparative approach relying on diffusion MRI based fiber-tracking to reconstruct whole-brain structural connectomes and explore its evolution.
