Title: Investigating the Role of Coil Designs and Anatomical Variations in Cerebellar TMS

Abstract: Transcranial magnetic stimulation (TMS) is a non-invasive neuromodulation technique that is used for treating various neurological disorders such as major depressive disorder. TMS has been gaining popularity in the field of neurostimulation of cerebellum, since the cerebellum is a complex structure connected with almost the entire central nervous system and TMS has promise for non-invasively probing cerebellar function. Recent studies have discovered that the cerebellum plays an important role not only in motor planning and behavior but also in the cognitive domain. However, few studies have explored how different coil designs and anatomical variations affect the effectiveness of cerebellar TMS. Therefore, in this work we investigated the effects of cerebellar TMS with different coil designs positioning on several locations. Finite element modeling was conducted with Figure-of-8 coil and D-B80 coil. Each coil was positioned in the center, 1 cm and 3 cm to the left of center of the cerebellum and all the locations were tangential to the scalp at a distance of 5 mm. Furthermore, 50 MRI derived head models were used in the computer modelling to examine how anatomical variations affect the distribution and intensity of electric field in cerebellar TMS.
