![]() The well-developed type was observed in 27 cases (67.5%). The gyrus was classified as underdeveloped, when it was covered by the fimbria of the hippocampus (but clearly visible at the coronal section of the hippocampal formation), while the hypoplastic gyrus was not visible macroscopically under the fimbria of the hippocampus. The dentate gyrus was classified as well-developed, when it protruded completely from under the fimbria of the hippocampus. Forty formalin-fixed human cerebral hemispheres, obtained from bodies of donors without the history of neuropathological diseases, were included in the study. Thus, the purpose of this macroscopic cadaveric study was to describe the anatomical variations of the dentate gyrus. ![]() An understanding of the variable morphology of the dentate gyrus may be important for diagnostic neuroimaging. However, a detailed knowledge of the anatomical variations of this structure in normal adult brain is still lacking. Recent scientific papers indicate the clinical significance of the dentate gyrus. ![]()
