Rockel, A. J.; R. W. Hiorns & T. P. S. Powell (1980), "The Basic Uniformity in Structure of the Neocortex", Brain 103 (2): 221–244, DOI:10.1093/brain/103.2.221 [e]
- A well-cited paper concluding that
- "the intrinsic structure of the neocortex is basically more uniform than has been thought and that differences in cytoarchitecture and function reflect differences in connections."
- The cerebral cortex is organized in columns which are commonly referred to (in a wide variety of contexts) as cortical columns, though ontogentic columns (Rakic 1988) would be more precise
- The number of neurons underneath equally sized patches of cortical surface area is approximately identical (around 147,000 per ) across mammalian species, with the exception of the primary visual cortex in primates.
- Point number 3 has been refuted by a number of studies (e.g. Herculano-Houzel et al., 2008; see also references therein), as summarized by Rakic 2008.
