Rakic, Pasko (2008), "Confusing cortical columns", Proceedings of the National Academy of Sciences 105 (34): 12099-12100, DOI:10.1073/pnas.0807271105 ^[e]

Provides a commentary on Herculano-Houzel et al. (2008) and Rockel at al. (1980), citing the former as a convincing (albeit not surprising) refutation of the latter in which the cortical architecture was assumed to be basically uniform within a brain and across mammalian species.
