This image provides a sagittal view of white matter fiber tracts in the human brain obtained using Diffusion Spectral Imaging, a technique explored by the NIH Human Connectome Project and advanced by BRAIN Initiative projects. The work from which the image originated was from the lab of BRAIN-funded investigator, Lawrence Wald, Ph.D. (MGH/Martinos Center for Biomedical Imaging) Setsompop et al., 2013, Neuroimage. The image was provided by the National Institutes of Health, one of the federal agencies supporting the Initiative. For more information, on this initiative, see the article by Koroshetz et al.
