3D cytoarchitectonic map of the human mesial piriform region of the BigBrain (v2.1)

This dataset contains cytoarchitectonic maps of four areas of the mesial piriform region in the BigBrain dataset. The maps are based on reference delineations in serial histological sections of the BigBrain at 1 micron resolution in-plane, with a distance of sections typically not lower than 300 micrometers. The 3D cytoarchitectonic maps were created in two different approaches: (1) As first version, a 3D map of the area was created by interpolation of the respective reference delineations. (2) As a more advanced version, a 3D map was created using deep convolutional neural networks trained on the respective reference delineations. As a result, the latter version also includes delineations of the area in the sections in-between reference delineations. The 3D maps were transformed to the 3D reconstructed BigBrain space and are integrated into the Julich-Brain Cytoarchitectonic Atlas.
