    "abstract": "A formula for an average connectivity between cortical areas in mammals is\nderived. Based on comparative neuroanatomical data, it is found, surprisingly,\nthat this connectivity is either only weakly dependent or independent of brain\nsize. It is discussed how this formula can be used to estimate the average\nlength of axons in white matter. Other allometric relations, such as cortical\npatches and area sizes vs. brain size, are also provided. Finally, some\nfunctional implications, with an emphasis on efficient cortical computation,\nare discussed as well.",
