Material and methods. The research involved cerebella of 100 people of both sexes, who died of causes unrelated to brain pathology at the age of 20-95. The parasagittal sections of the cerebellum were investigated. Possible variations in the size, shape and peculiarities of branching of the white matter in the lobules IV-V of the cerebellar hemispheres were investigated. Results. Complex branched white matter is the basis of the IV-V lobules of human cerebellar hemispheres. The shape of the IV-V lobules is quite varied. Differences of the structure of these lobules depend on the characteristics of the branching of the white matter. The shape of the lobule depends on location of the section. Structure of the lobules is different on serial parasagittal sections. We described 2 variants of branching of the white matter of the hemispheric lobules IV-V at a distance 5 mm from midsagittal section (the 2nd variant is the most common) and 10 common variants of the shape of IV-V lobules (10 mm from midsagittal section); the third variant is the most common variant of the lobule IV; the first, second, and third variants are the most common shape variants of the lobule V. Conclusion. Described variants of the shape of the cerebellar lobules can be used as criteria standards of modern diagnostic imaging techniques for the diagnosis of various diseases of the CNS.Item Morphological changes in cerebellar vermis in cerebral circulation disorders(Видавництво ХНМУ, 2017) Мар’єнко, Наталія Іванівна; Maryenko, Nataliia; Dobrovolska, OlenaItem Fractal dimension and variant anatomy of the white matter of the human cerebellar hemisperes(Institute of Physical Education, Kazimierz Wielki University in Bydgoszcz, Poland, 2017) Мар’єнко, Наталія Іванівна; Maryenko, Nataliia; Степаненко, Олександр Юрійович; Stepanenko, OleksandrIntroduction. Morphological changes of the cerebellar lobules are found in many congenital and acquired diseases of the cerebellum, but the information on the normal structure of the cerebellar lobules do not take into account the peculiarities of individual anatomical variability, sex and age characteristics. Aim – to investigate anatomical variability and fractal dimension of the white matter of the human cerebellar hemispheres. Material and methods. The study involved 100 cerebella of people of both sexes, who died of causes unrelated to brain pathology (20–99 years old). Parasagittal sections of the cerebellar hemispheres were investigated. Results. On parasagittal sections number of main branches of white matter is very varied and depends on peculiarities of structure of the hemispheric lobules. It was found that there is individual variability of the structure of the human cerebellar hemispheres, namely white matter branching features. We described variants of the branching of the main branches of white matter of the human cerebellar hemispheres. Fractal dimension of the white matter was determined. The white matter of the cerebellum is typical quasi-fractal structure that can be objectively described using fractal dimension. Fractal index of the white matter of the cerebellar hemispheres varies from 1.119 to 1.519; average fractal index is 1.370. Fractal analysis can be used as an objective morphometric criterion for the diagnosis of various diseases of the cerebellum and other structures of the central nervous system. Conclusions. Described variants of the cerebellar lobules and fractal dimension can be used as criteria for modern diagnostic imaging techniques for the diagnosis of various diseases of the CNS. The data can be used as the basis for atlases of serial sections of the cerebellum.Item Morphological changes in cerebellar vermis in cerebral circulation disorders(ХНМУ, 2017) Мар’єнко, Наталія Іванівна; Марьенко, Наталия Ивановна; Maryenko, Nataliia; Добровольська, О.М.; Dobrovolska, OlenaItem Variant anatomy of the lobules of the posterior lobe of the human cerebellum(ХНМУ, 2016) Мар’єнко, Наталія Іванівна; Марьенко, Наталия Ивановна; Maryenko, Nataliia; Добровольська, О.М.; Dobrovolska, OlenaItem Morphological peculiarities of the cerebellum in acute cerebral circulatory disorders(ХНМУ, 2014-05) Степаненко, Олександр Юрійович; Степаненко, Александр Юрьевич; Stepanenko, Oleksandr; Мар’єнко, Наталія Іванівна; Марьенко, Наталия Ивановна; Maryenko, Nataliia
