Computer assisted morphometry of the posterior supratemporal surface of the cerebrum

Computer morphometry of the posterior supratemporal surface of the cerebrum, combined with a study of the gross anatomical topography of fifty brains were done. 64% of the specimens showed anatomical features of dominant left hemispere in the temporal speech region, 12% on the right, and 24% were unclassifiable. Morphometeric data on the area of the planum temporale, length of its border and the angle formed by the planum together with the angle of orientation of transverse temporal gyrus were evaluated and related to the gross anatomical classification. The possible application of morphometric data on cut slices of cross sectional brain imaging techniques were discussed
