Human Brain — Morphologic Differences in the Hemispheres Demonstrable by Carotid Arteriography
Abstract
Functional differences of the cerebral hemispheres are great, but few consistent morphologic differences have been noted. On carotid arteriograms and on coronal sections of brains through the posterior ends of the sylvian fissures, we found the parietal operculum to be more highly developed on the left than on the right in 38 of 44 persons. However, arteriograms suggested that in 15 of 18 left-handed persons right parietal opercularization is as great as on the left. The study showed definite morphologic differences between the right and left hemispheres in a region of major importance for language. Endocranial casts of a fossil skull suggest that these differences were present in Neanderthal man. Arteriography offers a method of studying anatomic hemispheric differences.

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.
