Anatomical Differences between the Neocortex of Man and Other Primates
Abstract
The anatomical differences in neocortex between man and the other primates are reviewed. It is found that man''s neocortex is roughly three times as great as would be expected for a primate of the same body size. In many respects, man''s neocortex does not differ from that of other primates and, where it does, the difference can be shown to be related to the differences in total size of neocortex. However, there is evidence for the anatomical specialization of the dominant hemisphere in man, suggesting that man''s brain is not simply a larger version of other primate brains.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
