International audience. Magnetic resonance imaging at 7 T and beyond, enables imaging the full cortex at isotropic resolutions below 0.5 mm. Allowing the study of intra-cortical features such as cortical layers. In order to describe and analyse these features, the cortex needs to be described in ways that respect its structure across its whole thickness. A method is proposed, that can partition the cortex into cortical traverses which follow the geometry of cortical columns. These traverses will be used in future work to extract local measurements of lamination patterns.Two properties make this method a good basis for studying cortical lamination:– Each region contains samples from the whole cortical thickness;– Each voxel appears in one, and only one traverse.
