The BigBrain is a microscopic resolution 3D model of a complete human brain, based on a 3D reconstruction from 7404 digitized histological brain sections (Amunts, Evans et al., Science 2013). It provides a highly detailed anatomical reference space at 20 micrometer (isotropic) spatial resolution. We provide maps of different structures, including neo- and allocortical cytoarchitectonic areas and subcortical nuclei (Amunts et al.) as well as maps of cortical layers and brain surfaces (Wagstyl et al.).
