The human insula: Architectonic organization and postmortem MRI registration
Under a Creative Commons license
open access
Highlights
► Cytoarchitectonic maps of the human insula represented on unfolded maps and postmortem MRI. ► Seven subdivisions arranged from postero-dorsal (granular) to antero-ventral (agranular). ► Each subdivision expands over several insular gyri, the largest (dysgranular) over all. ► Gradient reversals point to boundaries of the insula with temporal and orbitofrontal cortices. ► The VENs area extends from the anterior agranular to anterior part of dysgranular insula.
