Abstract

Morphological studies of the various parts of the brain show certain morphological and morphometric differences in correlation with sex, so-called sexual dimorphism of the brain. Our research has been done on the cerebral hemispheres, taken from cadavers of both sexes and different age without pathological processes in the brain. The sample comprised 26 male brains and 16 female brains. We studied three primary grooves (sulcus cinguli, sulcus parietooccipitalis and sulcus calcarinus) of the medial surface of the human cerebral hemispheres. We conducted morphological typology of grooves and morphometric measurements of primary brain grooves length in relation to sex and side of hemisphere. The results showed a statistically significant sex difference in the cingulate sulcus length (p<0,05). Morphometric differences in sulcus parietooccipitalis and sulcus calcarinus were not statistically significant in relation to sex (p>0,05). Determined morphometric sexual dimorphism in cingulate sulcus length is significant because it implies the correlation between morphology and function of the explored areas of the cerebral cortex.
