A representative image with the color-coded regional boundaries. Web-based image processing software, MRICloud (www.MRICloud.org), was used to parcellate each T1-weighted image into five anatomical units that cover the whole brain: telencephalon (cyan); diencephalon (light green); mesencephalon (pink); metencephalon (yellow); and myelencephalon (orange). This is a fully automated method based on a diffeomorphic multi-atlas label fusion algorithm [9, 11, 25, 39, 44], which is among the most accurate methods for three-dimensional image parcellation.
