A new 3D myeloarchitectonic map of the human neocortex based on data from the Vogt –Vogt school

AbstractDuring the period extending from 1900 to 1970, Oskar and C écile Vogt and their numerous collaborators (‘the Vogt–Vogt school’) published a large number of studies on the myeloarchitecture of the human cerebral cortex. During the last decade, we have concerned ourselves with a detailed meta-analysis of these now almost totally forgotten studies, with the aim to bringing them into the modern era of science. This scrutiny yieldedinter alia a myeloarchitectonic map of the human neocortex, showing a parcellation into 182 areas (Nieuwenhuys et al. in Brain Struct Funct 220:2551 –2573, 2015; Erratum in Brain Struct Funct 220: 3753–3755, 2015). This map, termed 2D’15, which is based on data derived from all of the 20 publications constituting the myeloarchitectonic legacy of the Vogt–Vogt school, has the limitation that it is two-dimensional i.e. it shows only the pa rts of the cortex exposed at the free surface of the cerebral hemispheres and not the extensive stretches of cortex hidden in the cortical sulci. However, a limited set of data, derived from four of the 20 publications available, has enabled us to create a 3D map, showing the myeloarchitectonic parc ellation of the entire human neocortex. This map, designated as 3D′23, contains 182 areas: 64 frontal, 30 parietal, 6 insular, 19 occipital and 63 temporal. We have also prepared a 2D version (2D′23), of this 3D′23 map to serve as a link between the latter and our original 2D′15 map. Detaile d ...
