Asymmetry of anatomical parameters in MRI examination of the precentral gyrus and cerebellum

Studying the structure and functioning of various brain structures, as well as understanding their interaction, is a central task set for modern scientists in the field of neuromorphology. Although both hemispheres of the human brain develop simultaneously and strive for "sameness" at both the anatomical and functional levels, scientists have long established that there are certain morphofunctional differences between them. The aim of the study was to identify the severity of asymmetry of anatomical parameters during magnetic resonance imaging of the precentral gyrus and cerebellum. Object and methods . The analysis of the results of MR tomography of the brain of 53 people (28 men and 25 women) of the second period of adulthood without diseases and injuries of the organs of the central and peripheral nervous system, righthanded people was carried out. Results . When comparing the width of the precentral gyrus in both men and women, a tendency to their prevalence in the left hemisphere was revealed (p > 0.05). Similarly, an asymmetry in the cerebellum was revealed, consisting in the prevalence of indicators in its right hemisphere (p > 0.05). There is also a predominance of size in the sample of men (p > 0.05), which we explain by the larger size of the skull in comparison with the sample of women. Conclusion . The information obtained is of important both theoretical and practical importance for specifying information about certain structures of the brain, in particular its precentral gyrus and cerebellum, when using radiation diagnostic methods, and in clinical practice it can form the basis for identifying certain anatomical patterns of the hemispheres of the brain and cerebellum.
