- Abstract
Objective: The cerebellum is a part of the brain that plays a role in motor coordination, sensitivity and fine motor skills. Playing the guitar requires complex finger movements, precise hand-eye coordination and manual dexterity. The aim of this study is to investigate the changes in cerebellum and cerebellar lobule volumes between professional guitarists and non-guitarists. Methods: MR images of 10 guitarists and 10 non-guitarists (control group) were used in the study. High-resolution T1-weighted 3D Magnetization Prepared Rapid Gradient Echo (MPRAGE) images of individuals of similar age range were used for volumetric analysis of the cerebellum and its lobules. Data analysis was performed using "Volbrain (v1.0, https://volbrain. upv.es)-CERES (CEREbellum Segmentation)", a free online system that performs automatic segmentation. Results were obtained as the ratio of cerebellum and lobule volumes to total brain volume. Additionally, right and left asymmetry values were obtained and compared between groups using student t-test. Results: The mean cerebellar volume of the guitarists were found to be an average of 144.81±12.89 cm3; while those of the non-guitarists were 147.73±15.50 cm3. There was no statistically significant difference between the musician and the control group, both cerebellum and its lobule volumes (p>0.05). However, there was a statistically significant difference in Lobule V Asymmetry, Lobule V Gray Matter Asymmetry and Cerebellum Cortical Thickness Asymmetry values between the musician and control groups (p<0.05). Conclusion: According to our results, "Lobule V Asymmetry, Lobule V Gray Matter Asymmetry and Cerebellum Cortical Thickness Asymmetry" volume measurements of guitarists were found to be more asymmetric in right side than in left side in cerebellum.
