Diffusion MRI-based analysis of structural connectivity in mouse and chick brains. Representative diffusion MRI outputs of the mouse (left) and chick (right) brains, including 3D reconstructions, whole-brain and partial tractography, ODFs, and fractional anisotropy (FA) maps. ODFs visualize the directional complexity of water diffusion, providing information on local fiber orientation, whereas FA maps indicate white matter integrity. Tractography results illustrate global and region-specific axonal pathways. All images were processed using DSI Studio.
