Microscopic 3D model with maps of cytoarchitectonic structures
Use BigBrain (Amunts et al., 2013) to explore human brain architecture at the microscopic level. It is the highest resolution atlas of the human brain, with a nearly cellular isotropic resolution of 20 micrometer, and based on a reconstruction from 7404 digitized histological brain sections. Stained for cell bodies using a modified Silver staining, BigBrain provides a highly detailed anatomical reference space which resolves individual cortical layers and large cell bodies. We provide detailed 3D maps of cortical layers (Wagstyl et al., 2020) that were automatically computed based on cortical intensity profiles, as well as maps of cytoarchitectonic areas created with support of machine learning algorithms (Spitzer et al., 2018). The border definitions match those of the Julich-Brain cytoarchitectonic atlas (Amunts & Zilles, 2015) and are linked to the corresponding probabilistic maps in MNI space.
