Panizzon, M.S.; C. Fennema-Notestine & L.T. Eyler et al. (2009), "Distinct Genetic Influences on Cortical Surface Area and Cortical Thickness", Cerebral Cortex (in press), DOI:10.1093/cercor/bhp026 ^[e]

A brain morphometric analysis of neuroimaging data from the Vietnam Era Twin Registry, demonstrating that cortical thickness and cortical surface area contribute independently to total cortical grey matter in human adult males. This goes conform with the idea of ontogentic columns in the cerebral cortex: The number of cells within such a column would be reflected in cortical thickness, while the number of columns would be reflected in cortical surface area.
