We characterized the prevalence of bottleneck regions, or where multiple white matter pathways of the brain converge and subsequently diverge. These are areas of the brain that present challenges for diffusion tractography, yet represent information highways where dense bundles flow together. Here, we make available bottleneck maps of the brain in a standard space, and provide a map of these junction areas to be used in future studies of the brain.
